Kilograms to short tons (kg to ton)

One kilogram is 0.00110231131 US short tons. Exact in principle (a short ton is exactly 2,000 pounds and a pound exactly 0.45359237 kg), and unround because the pound is.

Worked through: 1,500 kg x 0.0011023113 = 1.65347 ton.

Going the other way, one short ton is 907.18474 kilograms.

For mental arithmetic: Divide by 1,000 and add 10%. Or divide by 907.

A metric figure read as American tons is about 10% low, and that is the error to look for. A 1,000 kg load is 1.10 short tons, and a truck carrying 20,000 kg is carrying 22.05 short tons. Calling it '20 tons' to an American dispatcher understates it by more than two tons, which on a weight-limited road or bridge is not a rounding error. If the reader is outside the US, the ton they mean is almost certainly the metric tonne, which is the kilogram figure divided by a thousand: 20,000 kg is 20 t. That is a separate page here, kilograms to metric tonnes.

Precision is worth matching to the input. A measurement given as 100 kg carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.
