Factors come from the stored source family and are not derived from rounded display values.
UnitCloud keeps calculating with stored factors and rounds only the displayed output by selected precision.
Do not use as the sole basis for official, medical, safety-critical or contractual decisions.
Citation note: UnitCloud, conversion with formula, sources current as of May 2026. Velocidade. Source basis: BIPM SI Brochure · NIST Guide to SI Appendix B.
