How to convert 640 yards to meters?

We know (by definition) that: 1 yd = 0.9144 m.

We can set up a proportion to solve for the number of meters.

1 yd / 640 yd = 0.9144 m / x m

Now, we cross multiply to solve for our unknown x:

x m = (640 yd / 1 yd) * 0.9144 m → x m = 585.216 m

Conclusion:

640 yd = 585.216 m
