PC builds and power supplies, storage and transfer times, networks and password strength, screen and print resolution, cloud and AI bills, batteries and electronics — the numbers behind the hardware and software you run, with the source behind every constant.

¿Qué necesitás resolver?
How long a battery in amp-hours or milliamp-hours will run your load, what DC supply the circuit needs, whether a speaker wiring plan is safe for the amplifier, what angle a servo pulse gives, a stepper motor’s resolution, inductive and capacitive reactance, and what a 3D printed part costs in dollars.
8 calculadoras How much space is this, and how long will it take?Convert bytes, KB, MB, GB and TB in binary or decimal, work out usable RAID capacity and what redundancy costs you, measure a compression ratio, estimate a git repository’s size and how long a file takes to copy over USB.
5 calculadoras Is my network — and my password — up to the job?Work out how many hosts a CIDR prefix gives you, which Ethernet category covers your run, which WiFi channel to sit on, what ping your distance allows, whether your Core Web Vitals pass, and how long a password or a bcrypt hash resists brute force.
7 calculadoras What PC do I need, and what power supply does it take?What PC you need for a target frame rate, how many watts it pulls, what power supply that requires, how much RAM your workload wants, whether you have thermal headroom to overclock, and how long a UPS keeps it alive.
5 calculadoras What resolution do I actually need?Work out the pixel density of a screen and whether it counts as Retina, how many pixels you need to print sharply at a given size in inches, and how heavy a JPEG will be at a given quality setting.
3 calculadoras What will this cost me to run per month?What a cloud instance costs per month in dollars, what your LLM API bill comes to, which image-generation plan fits, how many database connections your pool should hold, how long an algorithm takes at scale and how many person-months a codebase represents.
