Unit Converters
Length, weight, temperature, volume, area, speed, pressure, energy, power and decimal and binary storage.
Converting a unit means multiplying by a factor — except when it does not. Temperature has its own formula, and storage has two unit families that look alike and are not: decimal MB is 1,000,000 bytes and binary MiB is 1,048,576. Each converter states the factor it used so the result can be checked, refuses units from different families, and never rounds halfway.
How to use these calculators
- 1Choose the source and target unit within the same family; mixing mass with length is refused instead of converted wrongly.
- 2For temperature, enter the value in the source scale — Kelvin takes no negative number.
- 3For storage, decide between decimal (kB, MB, GB) and binary (KiB, MiB, GiB) before comparing with the value your system shows.

Why does 1 GB not show as 1 GiB on my computer?
Because many systems display GiB with the GB label. 1 decimal GB is 1,000,000,000 bytes; 1 GiB is 1,073,741,824. The storage calculator shows both readings.
Does temperature conversion use multiplication?
No. Celsius, Fahrenheit and Kelvin have an offset beyond the scale, so the tool applies each pair's formula instead of a single factor.
