Conversion formula

The conversion factor from feet per second to meters per second is 0.3048, which means that 1 foot per second is equal to 0.3048 meters per second:

1 ft/s = 0.3048 m/s

To convert 686 feet per second into meters per second we have to multiply 686 by the conversion factor in order to get the velocity amount from feet per second to meters per second. We can also form a simple proportion to calculate the result:

1 ft/s → 0.3048 m/s

686 ft/s → V_(m/s)

Solve the above proportion to obtain the velocity V in meters per second:

V_(m/s) = 686 ft/s × 0.3048 m/s

V_(m/s) = 209.0928 m/s

The final result is:

686 ft/s → 209.0928 m/s

We conclude that 686 feet per second is equivalent to 209.0928 meters per second:

686 feet per second = 209.0928 meters per second

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter per second is equal to 0.0047825654446255 × 686 feet per second.

Another way is saying that 686 feet per second is equal to 1 ÷ 0.0047825654446255 meters per second.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that six hundred eighty-six feet per second is approximately two hundred nine point zero nine three meters per second:

686 ft/s ≅ 209.093 m/s

An alternative is also that one meter per second is approximately zero point zero zero five times six hundred eighty-six feet per second.
