When you need this conversion
- Buying anything sized abroad: screens, bike frames, luggage limits and clothing patterns switch between metric and imperial depending on where they were made.
- DIY and construction: timber, pipe diameters and fixings are stocked in one system or the other, and a plan drawn in one has to be ordered in the second.
- Travel and sport: race distances, altitudes and road signs change unit at almost every border.
Getting it right
The arithmetic is a single multiplication, so mistakes almost never come from the calculation itself — they come from the value that goes into it. Check that the figure you are converting really is in feet and not in a neighbouring unit, and that you have not already converted it once.
Sanity-check the direction of the result before you use it. One foot is 12 inches, so converting feet to inches should make the number larger. If it moved the other way, the conversion was applied backwards — the reverse converter is one click away.
