Najjednoduchsie na zapamatanie do buducna je to takto. Premienas km/h na m/s a to "/" v tom chap ako delenie, ako zlomok, co aj je. Popremienas ciastkovo zlava doprava a teda, "km" -> "m" a "h" -> "s". 1km = 1000m a 1h = 3600s. Kedze chces "m" lomene "s" tak jednoducho das 1000m/3600s co je po zaokruhleni cca 0.28 m/s. Cize ak mas 2km/h a chces to na m/s, tak staci dat 2 * 0.28 = 0.56 m/s.
Ak by si to chcel opacne, m/s na km/h tak by to bolo obdobne, len zlava do prava by sa premienalo ako 1m = (1/1000) km a 1s = (1/3600) h. Potom rovankou uvahou ak chcem km/h, podelim (1/1000) / (1/3600) = 3,6km/h.
