Questions
How accurate are the conversions?
They use the exact international definitions: an inch is exactly 2.54 cm, a pound exactly 0.45359237 kg and a US gallon exactly 231 cubic inches. Results are shown to 10 significant digits, and Copy puts up to 12 on the clipboard.
Why are there two kinds of gallons and cups?
US and UK (imperial) measures differ: a US gallon is about 3.785 litres and a UK gallon 4.546 litres. Cups, pints and fluid ounces here are US measures, as used in most recipes online.
What’s the difference between MB and MiB?
A megabyte (MB) is 1,000,000 bytes, as used by drive makers and most operating systems’ storage labels. A mebibyte (MiB) is 1,048,576 bytes (1024²), which Windows shows as “MB”. That’s why a 1 TB drive appears as about 931 GB.
