Intro to the Metric system
- We use measurement to quantify (apply a number) to the size, shape,
weight of something.
- Units of measurement
o How we quantify something
o Common units of measurement
 Centimeter (cm), millimeter (mm), kilometers(km),
Hectometer(hm), decameter(dm), ounces(oz), milliliters(ml),
pounds(lb)
- Invented by people to be able to communicate the size, shape, or weight of
something.
- Standardized units
o They match official standard amounts that can be measured over and
over again to give exactly the same result.
The metric system uses the POWERS OF 10 and the base unit of METER.
The prefix of the unit tells us which power of 10 the measurement is using.
- Prefix is the word before the unit of measurement.
- EX: CENTImeter
DISTANCE
Kilo- x 1,000 meters (1,000 times bigger than 1 meter)
Hecto- x 100 meters (100 times bigger than 1 meter)
Deka- x 10 meters (10 times bigger than 1 meter)
Meter
Deci- ÷ 10 meters (10 times smaller than 1 meter)
Centi- ÷ 100 (100 times smaller than 1 meter)
Milli- ÷ 1,000 (1,000 times smaller than 1 meter)
1000.000
km hm dam m dm cm mm
1 Kilo = 1000m
1 hectometer =100m
1 deka = 10m
1 deci = 0.10m
1 centi = 0.0100m
1 milli = 0.0010m
MASS in the Metric System
- The weight
- Is how much actual matter the object contains.
- Measured in grams (g)
Different prefixes are applied to the base unit of GRAM to indicate the mass of
something.
1 gram = 1cm3 of water (cubed = volume)
Kilo- x 1,000 grams (1,000 times bigger than 1 gram)
Hecto- x 100 grams (100 times bigger than 1 gram)
Deka- x 10 grams (10 times bigger than 1 gram)
GRAM
Deci- ÷ 10 grams (10 times smaller than 1 gram)
Centi- ÷ 100 grams (100 times smaller than 1 gram)
Milli- ÷ 1,000 grams (1,000 times smaller than 1 gram)
1000.000
