The metric system

SI/MetricThe international system of units (SI) is a version of the metric system that modern scientists use. WE DO NOT USE THE STANDARD SYSTEM IN SCIENCE!

Volume Cubic centimeters OR Liters

Length• Length is measured in meters

Kilometers 1000Hectometers 100

Dekameters 10Meters

Decimeters 0.1Centimeters 0.01

Millimeters 0.001

Mass• Mass is measured in grams

Kilograms 1000Hectograms 100

Dekagrams 10Grams

Decigrams 0.1Centigrams 0.01

Milligrams 0.001

Volume• Volume is measured in Liters OR cm³

Kiloliters 1000Hectoliters 100

Dekaliters 10Liters

Deciliters 0.1Centiliters 0.01

Milliliters 0.001

Other SI Units• Time is measured in seconds (milliseconds are also

often used)

• Weight is measured in Newtons

• Temperature is measured in Celsius or Kelvin

• Since each step is ten times or one-tenth as much as the step on either side, we have:1 kilometer = 10 hectometers = 100 dekameters = 1000 meters = 10 000 decimeters = 100 000 centimeters = 1 000 000 millimeters

• Or: 1 milliliter = 0.1 centiliters = 0.01 deciliters = 0.001 liters = 0.000 1 dekaliters = 0.000 01 hectoliters = 0.000 001 kiloliters

Density• mass ÷ volume = density• grams ÷ cm³ = g/ cm³ OR grams ÷ Liters = g/ L

Which ones will float and which ones will sink?

What makes me float? Hmmm . . .

there was a really talkative student. Mrs. Supan’s evil twin taught this student and she knew that the talkative student needed to be taught a lesson. She found a roll of duct tape that measured 44.5 cm. The talkative student’s mouth measured 150.4 mm. Mrs. Supan’s evil twin wondered if she had enough tape to cover . . .
