1 Metric Ton = 1000000 Gram

Key Formulas

Kilogram → Pound

lb = kg × 2.20462

Pound → Kilogram

kg = lb × 0.453592

Gram → Ounce

oz = g × 0.035274

Ounce → Gram

g = oz × 28.3495

Formula

g = t × 1000000

The 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.
