Unit converter

Yards to metres.

Convert yd to m and m to yd. Type in either box and the other follows. Athletics tracks, swimming pools and fabric are the places this still comes up — and the yard is the unit the inch and foot are actually defined from.

Definitions

  • The yard is exactly 0.9144 m by definition — the anchor from which the inch, foot and mile all follow.
  • The metre is the SI base unit of length, defined by fixing the speed of light at 299 792 458 m/s.
  • This conversion is exact by definition. 1 yd = 0.9144 m.
  • The metre is SI; every imperial and US customary length here is defined exactly in terms of it by the 1959 international yard and pound agreement.

How it works

One direction multiplies and the other divides by the same number, so nothing is lost by going back and forth.

The value passes through m, the unit every other length & distance unit on the site is defined against, rather than a number written into this page on its own. That is why the figure here, the figure in the table above and the general length & distance converter always agree.

Display precision limits significant figures rather than decimal places, because one fixed number of decimals is useless across a range this wide. Very large and very small results switch to scientific notation with a proper superscript exponent. The editable box always holds a plain number at full working precision, so you can carry on from either side.

Common questions this answers: how many metres in a yard (0.9144), how many yards in a metre (1.09361), and what 100 yd is in metres (91.44 m).
