Convert US tons to Carats
1 US ton is 4,535,923.7 ct. One US ton is exactly 4535923.7 carats.
One US ton is 4.5359 × 10^+6 carats. To convert US tons to carats, multiply by 4.5359 × 10^+6; to go the other way, divide by 4.5359 × 10^+6 or multiply by 2.2046 × 10^-7. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Handbook 44. The short ton: 2,000 pounds.

What is a US ton?
The short ton: 2,000 pounds. A metric tonne is about 10% heavier and a British long ton about 12%.
What is a carat?
Exactly 200 milligrams, fixed by international agreement in 1907 after centuries of local carats. It weighs a gemstone; the karat that grades gold is a different word for a different thing — purity in twenty-fourths.
How many carats are in a US ton?
One US ton is 4.5359 × 10^+6 carats. Going the other way, one carat is 2.2046 × 10^-7 US tons. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
