Frequently Asked Questions

When should I round a measurement?

Carry the measured values and conversion factors through the calculation first. Round the final result to a precision justified by the original measurements.

Why can a supplier’s quantity differ?

Measurement conventions, nominal sizes, density assumptions and purchase rounding can change a practical quantity. Compare the units and assumptions before comparing the numbers.
