Frequently asked questions
How accurate are the results?
Calculations use the defined conversion factors, e.g. 1 inch = 2.54 cm and 1 pound (lb) = 0.45359237 kg. Six significant digits are shown.
How much is a pound?
The English pound (lb) weighs 453.59 grams. In everyday use in Switzerland and Germany, “ein Pfund” (a pound) often means 500 grams; both are available.
Why does my computer show fewer GB than on the box?
Manufacturers calculate 1 GB = 1000 MB, Windows uses 1024 (actually GiB). Windows therefore shows a 1 TB hard drive as about 931 “GB”.
