Weight Converter
Convert any mass from milligrams to US short tons. Uses the exact international definitions (1 lb = 453.59237 g, 1 oz = 1/16 lb, 1 stone = 14 lb, 1 US short ton = 2,000 lb), so imperial-to-metric conversions are precise rather than rounded. The table at the bottom shows your value in every common unit at once. Runs entirely in your browser.
