## 1. THE METRIC SYSTEM

- The metric system is a measurement system based on the powers of 10

### 1.1. UNITS

- Meter - length or distance [m]
- Gram - mass [g]
- Liter - volume [L]

### 1.2. METRIC UNITS:

The metric system has prefix modifiers that are multiples of 10

Kilo = K = 1000 Hecto = h = 100 Deca = da or dk = 10 [we use da] Unit = m, l, or g = 1 Deci = d = .1 [1/10] Centi = c = .01 [1/100] Milli = n = .001 [1/1000]

- Ex. dag = decagram, dam = decameter
- Note: Deca = 10, Deci = .1 or 1/10

### 1.3. CONVERSION OF UNITS

- To change from a larger unit to a smaller unit, you go right

1 km x 1000 = 1000 m 1 km x 100 = 100 cm 1 cm x 10 = 10 dam

- To change back, we go left
- note: K H D U D C H
