Quintal to Metric Ton Calculator
A quintal is a unit of mass widely used in agriculture, commodity trading, and logistics. In the metric system, 1 metric quintal (q) equals exactly 100 kilograms, so 1 metric ton (t) equals exactly 10 quintals. The conversion is definitional — no rounding involved. The quintal sits at a convenient middle ground between the kilogram (too small for trade quotes) and the metric ton (too large for individual producer transactions). It remains the working unit in South American (Argentina, Brazil), European, Indian, and Middle Eastern grain markets, where wheat, corn, soybean, rice, and barley prices are typically quoted as "per quintal" at the farm gate, while export contracts, USDA WASDE reports, and FAO statistics use metric tons. > ⚠️ Regional warning: The word "quintal" has historical ambiguity. In older US/UK trade, a "short quintal" (hundredweight) = 100 avoirdupois pounds ≈ 45.36 kg — less than half the metric quintal. Today, the FAO, EU, and international commodity markets use 100 kg. Always confirm which definition applies before signing a contract.
1 metric quintal = 100 kg = 0.1 metric tons. To convert quintals to metric tons, multiply by 0.1 (or divide by 10). To convert metric tons to quintals, multiply by 10. Example: 350 quintals = 35 metric tons.
When to use this calculator
- A grain farmer harvests 480 quintals of soybeans and needs to quote the shipment in metric tons for an export contract: 480 q ÷ 10 = exactly 48 metric tons.
- A fertilizer distributor prices ammonium nitrate at $28 per quintal — to find the cost per metric ton: $28 × 10 = $280/t.
- A commodity analyst converts USDA crop-production figures (metric tons) back to quintals to compare with regional q/ha yield statistics: 12 t/ha corn = 120 q/ha.
- An international logistics company calculates freight on a 7.5 metric ton rice cargo and needs the equivalent in quintals for local customs: 7.5 t × 10 = 75 quintals.
- A wheat broker handling a 2,500 metric ton parcel must list it in quintals on FOB documentation: 2,500 t × 10 = 25,000 quintals.
- An agronomist comparing a French wheat trial yielding 92 q/ha against a USDA reference of 9.0 t/ha: 92 q/ha ÷ 10 = 9.2 t/ha — slightly above the US benchmark.
- A sugar mill contracted to deliver 1,800 quintals of refined sugar reconciles the metric ton figure for the invoice: 1,800 q ÷ 10 = 180 metric tons.
- A farm accountant projecting income from a 250-hectare farm yielding 55 q/ha of corn for a bank loan: 250 ha × 55 q/ha = 13,750 q = 1,375 metric tons.
Example: soybean harvest export
- Input: 350 metric quintals (qq) of soybeans
- Apply formula: 350 qq × 0.1 = 35 metric tons
- Result: 350 qq = 35 t = 35,000 kg
How it works
2 min readHow the Conversion Works
The conversion between quintals (q) and metric tons (t) is exact and defined by the International System of Units (SI):
1 quintal (q) = 100 kg
1 metric ton (t) = 1,000 kg
Quintals → Metric Tons:
metric_tons = quintals × 0.1
(equivalently: metric_tons = quintals ÷ 10)
Metric Tons → Quintals:
quintals = metric_tons × 10Because both units are anchored to the kilogram, the conversion factor is perfectly exact — no rounding error.

Yield Conversion: q/ha to t/ha
To convert quintals per hectare (q/ha) to metric tons per hectare (t/ha), divide by 10:
| Crop | Typical yield (q/ha) | Equivalent (t/ha) |
|---|---|---|
| Wheat (EU) | 70–80 | 7.0–8.0 |
| Corn (US) | 100–120 | 10.0–12.0 |
| Soybeans (AR) | 28–32 | 2.8–3.2 |

Worked Examples
Example 1 — Wheat harvest:
A Kansas farm produces 320 quintals of hard red winter wheat. For CBOT export: 320 q × 0.1 = 32 metric tons. At $210/t: 32 × $210 = $6,720.
Example 2 — Fertilizer purchase:
Urea is quoted at $35/quintal. A grower needs 4.5 metric tons: 4.5 t × 10 = 45 quintals. Total cost = 45 × $35 = $1,575.
Example 3 — Yield comparison:
A corn yield of 11 t/ha = 110 q/ha, enabling direct comparison with European or South American yield data in q/ha.

Common Mistakes
1. Confusing short quintal (100 lb ≈ 45.36 kg) with metric quintal (100 kg). Using the wrong base inflates or deflates the result by ~2.2×.
2. Mixing metric ton with short ton (US ton). Metric ton = 1,000 kg; US short ton ≈ 907.18 kg (~10.3% less).
3. Ignoring grain moisture content. Grain traded at standard moisture (corn 15.5%, wheat 13.5%) — always apply moisture correction before converting for invoicing purposes.
4. Rounding intermediate steps. When chaining conversions, round only at the final step to avoid compounding errors.
Frequently asked questions
How many quintals are in 1 metric ton?
Exactly 10 quintals equal 1 metric ton. Since 1 quintal = 100 kg and 1 metric ton = 1,000 kg, the ratio is 1,000 ÷ 100 = 10. This is a definitional conversion anchored to the SI kilogram — no rounding, no approximation, regardless of commodity.
How do I convert quintals to metric tons?
Multiply the number of quintals by 0.1 (or divide by 10). Examples: 50 q × 0.1 = 5 t; 250 q ÷ 10 = 25 t; 1,000 q = 100 t. For the reverse (metric tons to quintals), multiply by 10.
Is a 'quintal' the same everywhere in the world?
No. The metric quintal (international standard) = 100 kg. In older US/UK trade documents, 'quintal' sometimes meant 100 avoirdupois pounds ≈ 45.36 kg. Some Iberian/Latin American usage historically referred to ~46 kg (4 arrobas). The FAO, EU, USDA international comparisons, and commodity markets today use the 100 kg definition. Always verify before signing a contract.
What is the difference between a metric ton and a short ton (US ton)?
A metric ton = exactly 1,000 kg ≈ 2,204.6 lb. A US short ton = 2,000 lb ≈ 907.18 kg — about 10.2% less. International commodity trading (grains, oilseeds, fertilizers) uses metric tons. US domestic markets (steel scrap, coal) often use short tons. A shipment quoted as '500 tons' could be 500 short tons (453.6 metric tons) or 500 metric tons depending on the contract jurisdiction.
How do I convert quintals per hectare (q/ha) to metric tons per hectare (t/ha)?
Divide q/ha by 10 to get t/ha. Examples: wheat 45 q/ha = 4.5 t/ha; corn 92 q/ha = 9.2 t/ha; soybeans 32 q/ha = 3.2 t/ha. This is essential when comparing European or South American field trial results (often in q/ha) against FAO or USDA country-level statistics (in t/ha).
Why is the quintal used in agricultural pricing instead of metric tons?
Quintals (100 kg) provide a more manageable price figure for mid-scale farm quantities. Quoting wheat at $21/quintal is easier for a small producer to relate to a truckload than $210/metric ton. The unit is entrenched in Argentine, Brazilian, Uruguayan, French, Italian, Spanish, and Egyptian grain markets, and appears in FAO commodity statistics and EU intervention price reports.
Can I use this converter for commodities other than grain?
Yes. The quintal-to-100-kg relationship applies universally: fertilizers (urea, DAP, potash), sugar, cotton, coffee and any bulk commodity measured by mass. However, metals are almost exclusively quoted in metric tons (or kg for precious metals), so quintals rarely appear outside agriculture and food commodities.
What is the relationship between a quintal and a hundredweight (cwt)?
A US short hundredweight (cwt) = 100 lb ≈ 45.36 kg. A UK long hundredweight = 112 lb ≈ 50.80 kg. Neither equals the metric quintal of 100 kg (≈ 220.46 lb). Do not substitute cwt for metric quintal — the error is approximately 2.2×. Always check the contract's unit definition clause.
How does grain moisture content affect the conversion in practice?
The quintal-to-metric-ton conversion is mass-exact, but commercial grain weight depends on standard moisture: wheat 13.5%, corn 15.5%, soybeans 13%, rice 14%. Field measurement at 18% moisture must be discounted: corrected weight = actual weight × (1 − actual moisture) ÷ (1 − standard moisture). So 100 q corn at 18% = 100 × 0.82 ÷ 0.845 ≈ 97 q at 15.5%. Apply moisture correction before converting for invoicing.
How does the USDA report crop production — quintals or metric tons?
The USDA NASS reports US production in short tons or bushels domestically. Its international comparisons (via FAS/WASDE) use metric tons. Agronomic literature uses q/ha or t/ha interchangeably — divide q/ha by 10 to get t/ha. For US-to-metric conversion, apply the crop-specific test weight before converting (grain density varies by crop).
Are quintal-to-metric-ton conversions always exact, or are there rounding issues?
All conversions are mathematically exact because both units are defined SI multiples of the kilogram. 7.35 q = exactly 0.735 t; 142.6 q = exactly 14.26 t. Apparent rounding only arises if the original weight was already a rounded approximation (e.g., a truck scale reading). For invoicing and customs, the unrounded conversion is legally precise.
Why do European grain markets use quintals while US markets prefer bushels?
Bushels are volumetric units standardized into weight: wheat 60 lb/bu, corn 56 lb/bu, soybeans 60 lb/bu. This creates per-crop complexity absent in the SI metric quintal, which works identically for every commodity. Europe adopted metric units early and standardized on the kilogram-based quintal. Today CBOT futures quote in bushels; MATIF (Paris wheat), FAO, and most non-US exchanges quote in metric tons.
