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 690 feet per second into meters per second we have to multiply 690 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

690 ft/s → V_(m/s)

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

V_(m/s) = 690 ft/s × 0.3048 m/s

V_(m/s) = 210.312 m/s

The final result is:

690 ft/s → 210.312 m/s

We conclude that 690 feet per second is equivalent to 210.312 meters per second:

690 feet per second = 210.312 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 0.0047548404275553 × 690 feet per second.

Another way is saying that 690 feet per second is equal to 1 ÷ 0.0047548404275553 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 ninety feet per second is approximately two hundred ten point three one two meters per second:

690 ft/s ≅ 210.312 m/s

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