Mm to Inches Converter FAQ
How exact is the factor?
It is the internationally defined value (0.0393700787) — fixed physics/definition, so this page can never go stale. Rounding happens only at display.
Why a dedicated page for one pair?
Because this is how people actually search — one pair, one job, zero menu-diving. The full multi-unit converter next door covers everything else.
