Ex: How many grams are equal to 500 milligram (MG)?
X g = 500mg 1g = 1000mg
X g = 500 mg X 1g
1000mg= 0.5 gram
OR ½ gram
Metric Cont’d
Example: How many milligrams are in 2 kilograms?
X mg = 2kg 1kg = 1000 g 1000 g = 1g 1g = 1000 mg Xmg = 2kg x 1000g x 1000mg 1 kg 1g 2 x1000x1000mg 2, 000,000 mg
= 2kg 1 1
Metric Cont’d
Example: How many micrograms are equal to 0.0005 kg?
1kg =1000g 1g =1000mg 1mg = 1000ug Xug= 0.0005kg x 1000g x 1000mg x 1000ug 1kg 1g 1mg
Xug= 0.0005x1000x1000x1000ug =500,000ug 1 x 1 x 1 500,000 ug = 0.0005 kg

The metric system is a system of weights and measurements based on meter (m), gram (g), and liters (L).
The metric system uses prefixes eg kilo, milli, micro.
Main thing to remember is that ml/ cc is the same thing.
