Question

convert 54 km / hr into m/s​

Answer 1

Answer:

15

As with any conversion, you multiply by conversion factors to remove (cancel) the units you don’t want, and insert the units you do want. A conversion factor is defined as a number with a numerator and denominator representing the same quantity, but using different units. So since the numerator and denominator are, in that sense the same, the conversion factor is in that sense equal to 1, and so will change the units, but not the underlying quantity.

To change 54 km/h to m/s, you would proceed as follows:

541kmh×10001mkm×160hmin×160mins=540003600ms=  15 m/s

If you study that carefully and understand what cancels what and why, you’ll never have to search for a conversion formula for the rest of your life.
