27Enter the number and choose the unit you are starting from.
All units update at once, so you can compare metric and imperial without converting twice.
Each row copies individually with its symbol attached.
The inch, foot, yard and mile are all defined in terms of the metre, so these conversions are exact rather than approximate.
Seeing both systems at once is what you actually need when translating between a specification and a tape measure.
Nautical miles, micrometres and nanometres are there for navigation and engineering, not just the everyday units.
A focused converter for distance and length. Enter one value and read every other unit at once — metric and imperial side by side, including nautical miles for navigation and micrometres for engineering work. The definitions used are exact: an inch is 25.4 millimetres by international agreement, a mile is 1609.344 metres, which means converting back and forth returns exactly the value you started with.
