## 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 40.3 feet per second into kilometers per hour we have to multiply 40.3 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

40.3 ft/s → V(km/h)

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

V(km/h) = 40.3 ft/s × 1.0972799999991 km/h

V(km/h) = 44.220383999965 km/h

The final result is:

40.3 ft/s → 44.220383999965 km/h

We conclude that 40.3 feet per second is equivalent to 44.220383999965 kilometers per hour:

40.3 feet per second = 44.220383999965 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 0.022614005341989 × 40.3 feet per second.

Another way is saying that 40.3 feet per second is equal to 1 ÷ 0.022614005341989 kilometers per hour.

## Approximate result

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

40.3 ft/s ≅ 44.22 km/h

An alternative is also that one kilometer per hour is approximately zero point zero two three times forty point three feet per second.
