Expanding the metric system with prefixes
In the metric system, other units are named by using prefixes such as kilo, hecto, deka, deci, centi, and milli etc...
1 kilo = one thousand and the symbol we use is k
For example, 1 kilometer = 1000 meters
6 kilometers = 6000 meters
0.5 kilometer = 500 meters
1 hecto = one hundred and the symbol we use is h
1 hectogram = 100 grams
5 hectograms = 500 grams
10 hectograms = 1000 grams
1 deka = ten and the symbol we use is da
1 dekameter = 10 meters
0.5 dekameter = 5 meters
2 dekameters = 20 meters
1 deci = one-tenth and the unit is d
1 deciliter = 0.1 liter
10 deciliters = 1 liter
20 deciliters = 2 liters
1 centi = one-hundredth and the unit is c
1 centimeter = 0.01 meter
10 centimeters = 0.1 meter
70 centimeters = 0.7 meter
1 milli = one-thousandth and the unit is m
1 millimeter = 0.001 meter
1000 millimeters = 1 meter
3000 millimeters = 3 meters
