## 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 2.8 feet per second into kilometers per hour we have to multiply 2.8 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

2.8 ft/s → V(km/h)

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

V(km/h) = 2.8 ft/s × 1.0972799999991 km/h

V(km/h) = 3.0723839999975 km/h

The final result is:

2.8 ft/s → 3.0723839999975 km/h

We conclude that 2.8 feet per second is equivalent to 3.0723839999975 kilometers per hour:

2.8 feet per second = 3.0723839999975 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 0.32548014831505 × 2.8 feet per second.

Another way is saying that 2.8 feet per second is equal to 1 ÷ 0.32548014831505 kilometers per hour.

## Approximate result

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

2.8 ft/s ≅ 3.072 km/h

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