    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.
