Convert Pounds to US tons

1 pound is 0.0005 ton. One pound is exactly 0.0005 US tons.

One pound is 5.0000 × 10^-4 US tons. To convert pounds to US tons, multiply by 5.0000 × 10^-4; to go the other way, divide by 5.0000 × 10^-4 or multiply by 2000. 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. Exactly 0.45359237 kilograms by international agreement, and sixteen ounces.
