Key Formulas
Kilogram → Pound
lb = kg × 2.20462Pound → Kilogram
kg = lb × 0.453592Gram → Ounce
oz = g × 0.035274Ounce → Gram
g = oz × 28.3495Formula
g = t × 1000000The metric tonne is 1000 kilograms, which is a million grams. Industrial documentation sometimes needs both — a shipping manifest might list cargo in tonnes for freight quotes, while the customs declaration might require gram-level precision. Converting between tonnes and grams means multiplying or dividing by a million.
