Key Formulas
Kilogram → Pound
lb = kg × 2.20462Pound → Kilogram
kg = lb × 0.453592Gram → Ounce
oz = g × 0.035274Ounce → Gram
g = oz × 28.3495Formula
t = g ÷ 1000000A metric tonne is 1000 kilograms, which equals one million grams. This conversion is relevant in mining, waste management, and industrial manufacturing where large quantities of raw materials are tracked. A quarry might produce thousands of tonnes of aggregate per day, while a recycling plant might track input in millions of grams that need converting to tonnes for reporting.
