Tonne (t). A tonne (metric ton) is 1,000 kilograms, used for vehicles, cargo, steel and crops.
Pennyweight (dwt). A pennyweight is 1/20 of a troy ounce (1.555 g), used by jewellers.
There are 643,015 pennyweights in one tonne.
Multiply the number of tonnes by 643,015. For example, 10 tonnes equal 6,430,150 pennyweights.
One pennyweight equals 1.55517 × 10⁻⁶ tonnes.
7,716,180 pennyweights. Other common values: 5 tonnes = 3,215,070 pennyweights and 100 tonnes = 64,301,500 pennyweights.
