How many tonnes are in one gram?

One gram equals 0.000001 t. The formula is t = g × 0.000001.

How do I convert grams to tonnes?

Multiply the value in grams by 0.000001. For example, 100 × 0.000001 = 0.0001 — so 100 g = 0.0001 t.

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.
