How to Convert Units

Basic Syntax

Enter a value with underscore and unit, then arrow to target unit:
5_kg → lb → 11.0231 lb
100_km → mi → 62.1371 mi
25_c → f → 77 f

Keyboard Shortcuts

ALPHA + SPC → types _ (underscore)
ALPHA + 0 → types (conversion arrow)
Example: 5 [ALPHA][SPC] kg [ALPHA][0] lb [ENTER]

Unit Arithmetic

Add or subtract compatible units:
5_km + 3_mi → km → 9.828 km
1_kg + 500_g → g → 1500 g
2_l - 500_ml → ml → 1500 ml

Display Unit Values

Just enter a unit value to display it:
5_kg → 5 kg
100_mph → 100 mph
