Weight Converter

1. Enter any weight. Type in any unit field and all 8 units recalculate immediately. No button needed.
2. Work with any unit as the starting point. Converting pounds to kilograms? Type in the pounds field. Need ounces from grams? Type in the grams field. Every field is both input and output.
3. Read all equivalents at once. All fields display simultaneously, so comparing metric tons to US tons or pounds to stone is a single glance.
4. Use decimals freely. Enter 2.5 pounds, 0.75 kg, or 185.5 lbs. The converter handles fractions and carries full precision throughout.

Example: a 165 lb person. Type 165 in the Pound field and instantly see: 74.8427 kg, 74,842.7 g, 74,842,700 mg, 0.0748427 t, 11.7857 st, 2,640 oz, 0.0825 US ton.

All conversions route through kilograms as the base unit:

Value in kg = Input × toKilograms factor
Result = Value in kg ÷ toKilograms factor

Key relationships: 1 pound = 16 ounces exactly. 1 stone = 14 pounds exactly. 1 US ton = 2,000 pounds exactly. 1 metric ton = 1,000 kg = 2,204.62 pounds. The metric ton is about 10% heavier than the US ton.
