How many kilograms are in one tonne?

One tonne equals 1,000 kg. The formula is kg = t × 1,000.

How do I convert tonnes to kilograms?

Multiply the value in tonnes by 1,000. For example, 100 × 1,000 = 100,000 — so 100 t = 100,000 kg.

Mass

Not all pounds are equal — how we weighed the world

Three different pounds in one kingdom, a Warsaw pound and a Prussian one, a probe burned up over Mars, a jetliner out of fuel over Canada — and a platinum cylinder near Paris that kept losing weight for a century, even though by definition it weighed exactly one kilogram. This is the history of mass units and its expensive mistakes.
