Convert a weight into every unit at once

Enter one value and a unit — milligrams, grams, kilograms, metric tonnes, ounces, pounds, or stone — and read it back in every unit at once. Each input is reduced to a canonical value in grams using exact factors (1 oz = 28.349523125 g, 1 lb = 453.59237 g, 1 st = 14 lb), then every output is derived from that base. Decimals are supported, but a mass cannot be negative.
