    I used to do it this way in highschool, but could never remember if it was divide by or multiply by 3.6

    Instead I now do it as you have shown, except it all goes in the same expression.

    10 km/h * 1000 m/km * 1h/3600s = 2.778 m/s

    No need for the extra steps. Slap it all in the same expression and put it in the calculator (being careful to check that the units cancel as intended)

      M/s is faster (lower number) than km/h so… That should give you enough explanation to understand whether you need to divide or multiply 3.6 when converting.

        It just never stuck. Just for me personally it’s easier to remember the base conversions of 1 km = 1000 m and 1 hr = 3600 and do the maths.

        Just my own personal preference, and when dealing with more complex units, is the only way.
