Engineering notes

Here ton means a metric tonne, not a US short ton or UK long ton.
These are mass units. Force in newtons or kilogram-force requires an appropriate gravity conversion.

Frequently asked questions FAQ

Is lb a mass or force unit here?

It is avoirdupois mass (lbm), not pound-force (lbf). Do not substitute the result directly into force equations.

Does display precision change the calculation?

No. Rounding is applied only to displayed results, not intermediate calculations. Small nonzero values use scientific notation. Consider the precision of the original measurements when interpreting results.
