Metric system of measurement
created about two hundred years ago by a group of French
scientists to simplify measurement.
metric system, each of the common kinds of measure -- length, weight,
capacity -- has one basic unit of measure. To measure
smaller amounts, divide the basic unit into parts of ten, a hundred, or
a thousand, and so on. To measure larger amounts, multiply the
basic unit by ten, a hundred, or a thousand, and so on.
1000 meters (m)
1 centimeter (cm) = .01 meter (m)
1 millimeter (mm) = .001 meter (m)
milliliter = .001 liter (l)
(kg) = 1000 grams (g)
1 milligram (mg) = .001 gram (g)
means thousand (1000)
Hecto means hundred (100)
Deca means ten (10)
means one-tenth (1/10)
Centi means one-hundredth (1/100)
Milli means one-thousandth (1/1000)

Convert 1.254 kilometers to meters.
Using a conversion

way to look at the problem:
When making metric conversions, arrange the prefixes
from largest to smallest:
gram or liter)
To convert 1.254
kilometers to meters, notice that in the chart above, the name meter
is three places to the right of the name kilo.
This implies that the decimal point in our number needs to be moved three
places to the right. The answer is 1254.0 meters.
