About inches and metres

Converting metres directly to inches skips the intermediate step through centimetres or feet, which is convenient for technical drawings and manufacturing specifications.

Inches are the working unit in much of American engineering and in international standards for screen sizes, fasteners and pipework, so metric designs often need translating.

Accuracy

One inch is exactly 0.0254 metres, so one metre is exactly 10000/254 inches — approximately 39.3701. The conversion is exact by definition.
