What this tool is for
This converts between metric and imperial and shows every related unit at once, so a height in centimetres appears in feet and inches together rather than as a decimal you then have to interpret. Cooking, travel, parcel weights and anything involving instructions written in another country all run into this.
How to convert units
- Choose what you are measuring, such as length, weight or temperature.
- Type your amount into the unit you have.
- Read the same amount in every other unit.
Questions
Which units can it handle?
Length, weight, volume, temperature, area, speed and data sizes, with the everyday units people actually meet in each.
Is a US cup the same as a UK one?
No, and the difference is enough to matter in baking. Cup measures vary by country, so check which one a recipe was written in.
Why does temperature behave differently from the rest?
Because its scales do not start at the same zero, so converting shifts as well as scales. That is why twice the degrees is not twice as warm.
Does it work without a connection?
Yes. These relationships are fixed and built in, so nothing needs to be fetched and nothing is sent.
