All units

Conversions use exact standard factors where they exist (like 25.4 mm to the inch) and standard scientific definitions elsewhere. Data sizes include both decimal (kB, MB) and binary (KiB, MiB) units — hard-drive makers use the first, operating systems often the second. Everything runs on your device.

Questions & answers

What can it convert?

Length, weight, temperature, speed, data size, area, volume, time, pressure, energy, angle, frequency, fuel economy, and cooking measures.

Can it convert cups to grams?

Yes — the cooking category converts between cups, tablespoons, millilitres, and grams using the density of the ingredient you pick.

Does it work offline?

Yes. All the conversions run in your browser with no connection needed, and nothing is uploaded.
