Conversion formula

The conversion factor from feet per second to kilometers per hour is 1.0972799999991, which means that 1 foot per second is equal to 1.0972799999991 kilometers per hour:

1 ft/s = 1.0972799999991 km/h

To convert 5.5 feet per second into kilometers per hour we have to multiply 5.5 by the conversion factor in order to get the velocity amount from feet per second to kilometers per hour. We can also form a simple proportion to calculate the result:

1 ft/s → 1.0972799999991 km/h

5.5 ft/s → V(km/h)

Solve the above proportion to obtain the velocity V in kilometers per hour:

V(km/h) = 5.5 ft/s × 1.0972799999991 km/h

V(km/h) = 6.0350399999952 km/h

The final result is:

5.5 ft/s → 6.0350399999952 km/h

We conclude that 5.5 feet per second is equivalent to 6.0350399999952 kilometers per hour:

5.5 feet per second = 6.0350399999952 kilometers per hour

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer per hour is equal to 0.16569898459675 × 5.5 feet per second.

Another way is saying that 5.5 feet per second is equal to 1 ÷ 0.16569898459675 kilometers per hour.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that five point five feet per second is approximately six point zero three five kilometers per hour:

5.5 ft/s ≅ 6.035 km/h

An alternative is also that one kilometer per hour is approximately zero point one six six times five point five feet per second.
