About Inch and Meter
The inch is defined as exactly 25.4 millimeters, one twelfth of a foot. Screen sizes, pipe diameters, and US manufacturing drawings are specified in inches. The meter is the SI base unit of length, defined since 1983 as the distance light travels in a vacuum in 1/299,792,458 of a second. Every other length unit on this site is defined in terms of it. One Inch equals 0.0254 Meters (1 in = 0.0254 m). Inch is used in screen and display sizes and in US manufacturing and plumbing specifications. Meter is used in architectural drawings and building codes outside the US.
Precision and Rounding:Length factors between metric and imperial units are exact by definition (1 ft = 0.3048 m since 1959), so any rounding error comes from display precision, not the factor. Two or three decimal places suit carpentry and DIY work; machining and surveying often require four or more.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
