Unit Conversion

Type an amount, a unit, to or in, and a target unit. A result row shows up above your launchers, with no keyword needed:

10 km to mi        → 10 km = 6.21371 mi
70f to c           → 70 °F = 21.1111 °C
5 GB in MB         → 5 GB = 5000 MB
3 cups to ml       → 3 cup = 709.765 ml
1.5 hours to min   → 1.5 h = 90 min
100 km/h to mph    → 100 km/h = 62.1371 mph

Enter copies the number and Ctrl+Enter copies it with its unit. The row rounds to 6 significant digits; the copied value keeps 15, and whole numbers are copied exactly. Copying needs wl-copy, xclip or xsel.

Note

Unit conversion is on by default; see Configuration to turn it off.

Both units must measure the same thing, so 10 km to kg shows nothing. A target unit is required: 5 m alone keeps searching your launchers. Math expressions go to the calculator and currency conversions to the currency converter first.

Supported units

Unit names are case-insensitive, and most accept their full name and plural too (km, kilometer, kilometres).

Kind	Units
Length	mm, cm, m, km, in, ft, yd, mi, nmi
Mass	mg, g, kg, t (tonne), oz, lb, st (stone)
Volume	ml, cl, dl, l, cm3/cc, m3, tsp, tbsp, floz/fl oz, cup, pt, qt, gal
Temperature	c, f, k (also °C, celsius, fahrenheit, kelvin)
Data	b, B, kb, kB/KB, Mb, MB, Gb, GB, Tb, TB, PB, Kib, KiB, Mib, MiB, Gib, GiB, TiB
Time	ms, s, min, h, d, wk, yr
Speed	m/s, km/h (kph), mph, kn (knots), ft/s
Area	cm2, m2, km2, ha, ac, in2, ft2, yd2, mi2 (also sq ft and friends)

Cups, pints, quarts, gallons and fluid ounces are US customary. Prefix pints, quarts, gallons or fluid ounces with imp or uk for the imperial ones, as in 2 uk gal to l. A year is 365.25 days.

Data symbols are case-sensitive: a lowercase b means bits and an uppercase B means bytes, so Mb is a megabit and MB a megabyte. KB and kB are 1000 bytes, while KiB is 1024. Spelled-out names such as megabytes work in any case.
