Common examples
Frequently asked
What categories are supported?
Length, weight, temperature, area, volume, speed, data storage, and cooking — all sharing the same conversion data as the dedicated converters.
Are values exact?
Yes — international SI definitions are used, with display rounded to 4 decimals.
Why does cooking sometimes show '—'?
Volume↔weight conversions depend on the ingredient's density. Pick two volume units, or two weight units, for an exact answer.
Metric vs imperial vs US customary?
Metric uses meters, liters and grams. Imperial (UK) and US customary share names like “gallon” and “ounce” but differ in size — we use US customary by default.
Why is data tricky (KB vs KiB)?
Storage often uses binary multiples: 1 KiB = 1,024 bytes. Drives sometimes use decimal (1 KB = 1,000 bytes), which is why drive sizes look smaller in your OS.
Can I convert temperature with negatives?
Yes — negatives work for °C and °F. Kelvin is absolute and starts at 0 K.
