About Unit Converter

Convert length, mass, temperature, volume, area, speed, data and more across 14 categories — every unit updates at once, with the formula shown.

What it does

Type a value once and every unit in the category updates together, so you see the whole picture instead of converting one pair at a time. The conversion formula is shown alongside the result, which matters when you need to justify a number rather than just copy it.

Fourteen categories

Length, mass, temperature, volume, area, speed, time, digital storage, pressure, energy, power, angle, frequency and fuel economy — metric and imperial throughout, including the units that trip people up, like the difference between US and imperial gallons.

Common questions

Why is temperature handled differently from other units?
Most conversions are a single multiplication, but temperature scales have different zero points, so Celsius to Fahrenheit needs both a scale factor and an offset. The formula display shows this explicitly.
Are US and imperial gallons treated as the same unit?
No — they differ by about 20%, and conflating them is a classic source of error, so they are listed separately.
Does it handle data storage in powers of two?
Yes. Both decimal (kB = 1000 bytes) and binary (KiB = 1024 bytes) conventions are available, because the two disagree by a growing margin at larger sizes.
