Convert US tons to Grains

1 US ton is 14,000,000 gr. One US ton is exactly 14000000 grains.

One US ton is 14000000 grains. To convert US tons to grains, multiply by 14000000; to go the other way, divide by 14000000 or multiply by 7.1429 × 10^-8. The factor is exact rather than rounded: it follows from NIST Handbook 44. The short ton: 2,000 pounds.

How do you convert US tons to grains? The converter and the working

  1. 1.Take the measurement in US tons.
  2. 2.Multiply by 14000000 — that is how many grains fit in one US ton.
  3. 3.To go back the other way, divide by 14000000, or multiply by 7.1429 × 10^-8.

Worked example: 25 US tons to grains

Formula
ton × 14000000 = gr
Arithmetic
25 × 14000000 = 350,000,000 gr
Answer
25 ton = 350,000,000 gr

The factor is exact, so this figure is exact too — only the display is rounded.

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 grain?

Exactly 64.79891 milligrams, the unit both the avoirdupois and troy systems are built from. Bullet weights and powder charges are still measured in it, and so are some pharmaceutical doses.

How many grains are in a US ton?

One US ton is 14000000 grains, exactly. Going the other way, one grain is 7.1429 × 10^-8 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.

The whole group — 15 units with their symbols and the size of each one in kilograms — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a US ton.
