How to use Unit converter

Get started

1. 1

   Choose units and enter a value

   Tap the category to pick one, then tap a unit to change it. Type the value on the keypad: the answer updates as you type, and the swap key turns the pair around.

2. 2

   Choose a conversion layout

   Pick a screen in ⋮ › Screen layout: Pair and keypad, Every unit (one value in every unit of the category) or Conversion list (type “120 sq ft to m²” and keep a list to share).

Measure

3. 3

   Enter fractions or take the phone’s angle

   In feet and inches, type 5 ′ 7 ″ 3 / 8 for 5′ 7 3/8″; answers round to the inch fraction set in Display. Slope and Angle can take the tilt from the phone: tap Measure and lay the phone on the surface.
