How to use this calculator

  1. Enter the known values in the units shown. Results update as you type.
  2. Where results are editable, change one to solve backwards. Lock a value to hold it fixed.
  3. Use the worked example to check the method. Reset restores the starting fields.

Formula and method

1 international mile = 1,609.344 m = 5,280 ft = 1,760 yd. Compare eight distance fields together, with separate metric and customary unit selections. One international inch is exactly 25.4 mm.

1 international mile = 1,609.344 m = 5,280 ft = 1,760 yd

Assumptions and limitations

  • Compare eight distance fields together, with separate metric and customary unit selections. One international inch is exactly 25.4 mm.
  • These are linear lengths, not areas or volumes. Square and cubic units require squared and cubed conversion factors.
  • The arithmetic accepts signed values for directed differences. Physical heights and ordinary distances should be entered as nonnegative magnitudes. Display rounding does not improve the precision of a measurement.

Common questions

Can I convert back from the result?

Yes. Enter a known value in another field and leave the original field blank. Every field describes the same underlying length.

How should I read a compound length?

When a compound unit is selected, use colons between the displayed components. A decimal value in feet is not the same as feet followed by inches.
