Units to know for Chapter 1-3:

 

1.      Basic units: English system: pound, foot, yard, mile, quart, gallon, second

 

2.      Basic units: Metric system: meter, second, liter, gram

 

3.      Prefixes metric system: d (.1), c (.01) , m (.001), μ (.000001), k (1000). Thus:

1 km = 1000 m

1 m = 1,000,000 μm

1 m = 100 cm

1 m = 10 dm

4.      Derived units: Metric system: Newton, Joule, calorie

 

5.      Temperature: C, F, K
