How many meters per second in 257 kilometers per hour?

Conversion formula

The conversion factor from kilometers per hour to meters per second is 0.277777777778, which means that 1 kilometer per hour is equal to 0.277777777778 meters per second:

1 km/h = 0.277777777778 m/s

To convert 257 kilometers per hour into meters per second we have to multiply 257 by the conversion factor in order to get the velocity amount from kilometers per hour to meters per second. We can also form a simple proportion to calculate the result:

1 km/h → 0.277777777778 m/s

257 km/h → V_(m/s)

Solve the above proportion to obtain the velocity V in meters per second:

V_(m/s) = 257 km/h × 0.277777777778 m/s

V_(m/s) = 71.388888888946 m/s

The final result is:

257 km/h → 71.388888888946 m/s

We conclude that 257 kilometers per hour is equivalent to 71.388888888946 meters per second:

257 kilometers per hour = 71.388888888946 meters per second

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter per second is equal to 0.014007782101156 × 257 kilometers per hour.

Another way is saying that 257 kilometers per hour is equal to 1 ÷ 0.014007782101156 meters per second.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that two hundred fifty-seven kilometers per hour is approximately seventy-one point three eight nine meters per second:

257 km/h ≅ 71.389 m/s

An alternative is also that one meter per second is approximately zero point zero one four times two hundred fifty-seven kilometers per hour.

Conversion units

The units involved in this conversion are kilometers per hour and meters per second. This is how they are defined:

Kilometer per hour

The kilometre per hour (American English: kilometer per hour) is a unit of speed, expressing the number of kilometres travelled in one hour. The unit symbol is km/h. Worldwide, it is the most commonly used unit of speed on road signs and car speedometers. Although the metre was formally defined in 1799, the term "kilometres per hour" did not come into immediate use – the myriametre (10,000 metres) and myriametre per hour were preferred to kilometres and kilometres per hour.

Meter per second

Metre per second (American English: meter per second) is an SI derived unit of both speed (scalar) and velocity (vector quantity which specifies both magnitude and a specific direction), defined by distance in metres divided by time in seconds. The SI unit symbols are m·s−1, m s−1 or m/s sometimes (unofficially) abbreviated as "mps". Where metres per second are several orders of magnitude too slow to be convenient, such as in astronomical measurements, velocities may be given in kilometres per second, where 1 km/s is 1000 metres per second, sometimes unofficially abbreviated as "kps".
