Kilotonne (kt). A kilotonne is 1,000 tonnes (one million kilograms).
Carat (ct). The metric carat is 200 milligrams, the unit for diamonds and gemstones.
There are 5,000,000,000 carats in one kilotonne.
Multiply the number of kilotonnes by 5,000,000,000. For example, 10 kilotonnes equal 50,000,000,000 carats.
One carat equals 2 × 10⁻¹⁰ kilotonnes.
60,000,000,000 carats. Other common values: 5 kilotonnes = 25,000,000,000 carats and 100 kilotonnes = 500,000,000,000 carats.
