Unit Converter
Convert between units of length, weight, volume, temperature and more in one place.
One converter for everyday units
Everyday life keeps throwing unit conversions at you — a recipe in cups when you think in grams, a height in feet you need in centimetres, a distance in miles you want in kilometres. This handles the common families of units in one place, so you can switch between them without hunting for the right formula or a separate tool for each.
Pick the quantity, enter a value, and see it in the units you want.
Where conversions catch people out
A couple of things are worth watching. Temperature is the odd one out — it does not scale from zero like length or weight, so its conversion involves a shift as well as a factor, which is why you cannot simply multiply. And the US and imperial systems share names but not always sizes, most famously the gallon and the pint, which differ between the two. For the common conversions of daily life, though, entering a number and reading the result is all it takes.
Frequently asked questions
What units does it cover?
The common families — length, weight, volume, temperature, area, speed and more — for everyday conversions.
Why can't I convert temperature by just multiplying?
Because temperature scales do not start from a shared zero, so converting involves a shift as well as a factor.
