## 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 18.6 feet per second into kilometers per hour we have to multiply 18.6 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

18.6 ft/s → V(km/h)

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

V(km/h) = 18.6 ft/s × 1.0972799999991 km/h

V(km/h) = 20.409407999984 km/h

The final result is:

18.6 ft/s → 20.409407999984 km/h

We conclude that 18.6 feet per second is equivalent to 20.409407999984 kilometers per hour:

18.6 feet per second = 20.409407999984 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 0.048997011574309 × 18.6 feet per second.

Another way is saying that 18.6 feet per second is equal to 1 ÷ 0.048997011574309 kilometers per hour.

## Approximate result

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

18.6 ft/s ≅ 20.409 km/h

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