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 1.5 feet per second into kilometers per hour we have to multiply 1.5 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

1.5 ft/s → V(km/h)

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

V(km/h) = 1.5 ft/s × 1.0972799999991 km/h

V(km/h) = 1.6459199999987 km/h

The final result is:

1.5 ft/s → 1.6459199999987 km/h

We conclude that 1.5 feet per second is equivalent to 1.6459199999987 kilometers per hour:

1.5 feet per second = 1.6459199999987 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 0.60756294352143 × 1.5 feet per second.

Another way is saying that 1.5 feet per second is equal to 1 ÷ 0.60756294352143 kilometers per hour.

Approximate result

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

1.5 ft/s ≅ 1.646 km/h

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