pro tips
Multiply by a million: 0.5 tonnes is 500,000 g.
1 tonne is 1,000 kg, and 1 kg is 1,000 g — the ladder in two steps.
Industrial recipes rarely need this, but accounting systems sometimes do.
what it does
One tonne is 1,000,000 grams. Multiply tonnes by a million and the grams appear, which is how a freight weight becomes something a lab or a recipe can actually use.
It shows up when a shipment measured in tonnes has to be logged in grams for a system that only understands small units, when industrial quantities in tonnes meet a kitchen scale that reads grams, when recycling reported in tonnes needs to be reconciled with a granular inventory in grams, and in any audit where the tiny and the huge have to agree.
The shortcut moves the decimal six places right: 1 t is 1,000,000 g, 0.5 t is 500,000 g, 0.01 t is 10,000 g. Going through kilograms keeps it readable: tonnes to kilograms, then kilograms to grams.
Type any tonne value and the widget answers in grams instantly, with the math on screen. Click to copy, and swap when a gram measurement has to be rolled up into tonnes.
