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 840 feet per second into meters per second we have to multiply 840 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

840 ft/s → V_(m/s)

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

V_(m/s) = 840 ft/s × 0.3048 m/s

V_(m/s) = 256.032 m/s

The final result is:

840 ft/s → 256.032 m/s

We conclude that 840 feet per second is equivalent to 256.032 meters per second:

840 feet per second = 256.032 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 0.0039057617797775 × 840 feet per second.

Another way is saying that 840 feet per second is equal to 1 ÷ 0.0039057617797775 meters per second.

Approximate result

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

840 ft/s ≅ 256.032 m/s

An alternative is also that one meter per second is approximately zero point zero zero four times eight hundred forty feet per second.
