Speed in **kilometres per hour (km/h, km h ^{-1}):**

Result in **metres per second (m/s, m s ^{-1}):**

## How to convert speed from kilometres per hour to speed in metres per second?

*1 km/h ≈ 0.278 m/s*

*Metres per second (UK) = m/s = m s ^{-1} = m•s^{-1 }= meters per second (US) = mps *

*Kilometres per hour (UK) = km/h = km h ^{-1} = km•h^{-1 }= kilometers per hour (US) = kph*

Speed in metres per second is equal to speed in kilometres per hour divided by 3.6.

Formulas:

*metres per second = kilometres per hour / 3.6*

**(m/s)= (km/h) / 3.6**

*m**•**s ^{-1} = km*

*•*

*h*^{-1}/ 3.6

*υ _{m/s} =υ_{km/h} / 3.6*

* υ_{m/s}* – speed in metres per second;

* υ_{km/h}* – speed in kilometres per hour.

For example:

*Convert speed 36 km/h to m/s.*

Solution: *υ _{m/s} = υ_{km/h} / 3.6* = 36 / 3.6 = 10 m/s. Answer: 36 km/h = 10 m/s.

*Convert speed 54 km/h to m/s.*

Solution: *(m/s)= (km/h)** / 3.6* = 54 / 3.6 = 15 m/s. Answer: 54 km/h = 15 m/s

Convert speed 72 km•h^{-1} to m•s^{-1}.

Solution: *m•s ^{-1} = km•h^{-1} / 3.6* = 72 / 3.6 = 20 m•s

^{-1}. Answer: 72 km•h

^{-1}= 20 m•s
