Unit converter
Length, weight, temperature, data…
What it does
Converts a value in 12 categories: length, area, volume, weight, temperature, speed, time, data, data rate, cooking, angle and bases.
- Pick a category, type the value, pick the units; ⇅ swaps them. Tap the result to copy it.
- On the right, the value in every unit of the category: tap a line to make it the target.
- Data: GB (10⁹ bytes, as disk makers count) and GiB (2³⁰ bytes, as Windows shows). Data rate: Mb/s (bits, video and internet) and MB/s (bytes, disks): 8 bits make a byte.
- Cooking: a teaspoon is 5 ml and a tablespoon 15 ml; the cup and the fluid ounce are the US ones.
- Bases: whole numbers in binary, octal, decimal, hexadecimal or base 36, with no size limit. 0x, 0b and 0o prefixes, spaces and _ are accepted. Binary shows in groups of 4 bits.
