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 1686 feet per second into meters per second we have to multiply 1686 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

1686 ft/s → V_(m/s)

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

V_(m/s) = 1686 ft/s × 0.3048 m/s

V_(m/s) = 513.8928 m/s

The final result is:

1686 ft/s → 513.8928 m/s

We conclude that 1686 feet per second is equivalent to 513.8928 meters per second:

1686 feet per second = 513.8928 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 0.0019459311358322 × 1686 feet per second.

Another way is saying that 1686 feet per second is equal to 1 ÷ 0.0019459311358322 meters per second.

Approximate result

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

1686 ft/s ≅ 513.893 m/s

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