Converting length units
Length conversions all work through a single base unit — here, the meter. Each unit has a fixed size in meters (a foot is 0.3048 m, a mile is 1609.344 m), so converting means expressing the value in meters and then dividing by the target unit's size. That keeps metric and imperial conversions exact.
Metric and imperial in one place
Everyday work often mixes systems: a room measured in meters, a part spec in inches, a run tracked in miles. Converting between them by hand invites slips, especially with the odd imperial factors. Picking the two units and reading the answer removes that friction.
Exact factors, rounded display
The underlying factors are the internationally defined ones, so an inch is exactly 25.4 mm. The result is rounded for readability, but the math is done at full precision before rounding.
