Theory — how does the pounds-to-kg converter work?
The weight converter switches between pounds, kilograms, grams and ounces, using the exact ratio of one pound to 0.45359237 kilograms. A regular ounce weighs 28.349523125 grams, while a troy ounce, used for precious metals among other things, weighs 31.1034768 grams — the difference matters and the two should not be swapped without checking. For example, 10 pounds equal 4.5359237 kilograms. You can choose the ounce type and compare several values at once.
