Engineering converter · gauge-safe scope
Convert common metric and imperial project values while avoiding ambiguous wire-gauge assumptions.
Converter
Switch between common metric and imperial values without changing the underlying specification.
Pure unit conversion only. Wire gauge systems such as AWG, SWG and BWG are intentionally excluded because the same gauge number does not represent one universal diameter.
Scope
Round only at presentation; retain the original value in drawings and purchase documents.
mm, cm, m, inch and foot.
gram, kilogram, pound and metric tonne.
kg/m² and lb/ft².
Pa, kPa, MPa, bar and psi.
How to use the result
Use the result as a planning input, preserve the original assumptions, and ask the supplier to confirm product-specific values.
The converter applies fixed mathematical factors for length, mass, mass per area and pressure. It changes units, not the tolerance or precision of the source measurement.
Translating buyer drawings, datasheets and RFQs between metric and imperial working units.
The original numeric value, its unit, the target unit and enough retained precision to avoid cumulative rounding.
25.4 mm equals exactly 1 inch; keep 25.4 mm in the source record rather than replacing it with a prematurely rounded display value.
Using AWG, SWG or BWG as interchangeable diameter units, or adding decimal places that imply measurement accuracy not present in the source.
