Milligram (mg). A milligram is one thousandth of a gram, used for medicine doses and nutrition labels.
Kilotonne (kt). A kilotonne is 1,000 tonnes (one million kilograms).
There are 1 × 10⁻¹² kilotonnes in one milligram.
Multiply the number of milligrams by 1 × 10⁻¹². For example, 10 milligrams equal 1 × 10⁻¹¹ kilotonnes.
One kilotonne equals 1,000,000,000,000 milligrams.
1 × 10⁻⁹ kilotonnes. Other common values: 100 milligrams = 1 × 10⁻¹⁰ kilotonnes and 10,000 milligrams = 1 × 10⁻⁸ kilotonnes.
