1.1 use the following units: kilogram (kg), metre (m), metre/second (m/s), metre/second2 (m/s2), newton (N), second (s), newton per kilogram (N/kg), kilogram metre/second (kg m/s)

This is pretty simple and you will learn these units as you go along the course, when they become relevant:

Mass:
1,000g = 1kg
1,000kg = 1 ton

Weight:
Newton - N

Distance:
100cm = 1m
1,000 = 1km
Speed:
metre/ second - m/s
miles/hour - mph
kilometers/hour - km/h

Other:
metres/second2 - m/s2
newton/kilogram - n/kg
kilogram meter/second - kg m/s
