Accuracy in unit conversion depends on choosing the right tool, verifying results, and understanding the limits of precision. This guide covers the habits that prevent costly mistakes.

1. Verify conversion factors

Always cross-check critical conversions against a trusted reference. Small rounding differences compound in engineering and scientific workflows.

2. Mind significant figures

Inputs with limited precision should not produce overly precise outputs. Round results to the same number of significant figures as the least precise input.

3. Use the right category

Mixing categories—like treating volume as weight—produces invalid results. Temperature conversion also requires special handling because of offsets.
