### Metric System

The Scientific Way to Measure

• Meter (m)- measure length

• Gram (g)- measures mass

• Kelvin (k)- measure heat

• Second (s)- measures time

• Mole- (mol) measures particles ex, atoms molecules

• Liter (L) measures volume or cm3

• Micro (μ) 1/1,000,000 or 1.0 X 10-6

• Milli (m) 1/1000 or 1.0 x 10-3

• Centi (c) 1/100 or 1.0 x 10-2

• Deci (d) 1/10 or .1

• Deka (D) 10

• Hekto (H) 100

• Kilo (K) 1000 or 1.0 x 103

• Mega (M) 1,000,000 or 1.0 x 106

• Use conversion factors to convert from one unit to another

• Are expressed as fraction, which represent absolute relationships

• For example:

• 1 dollar/100 pennies, 1 dollar/4 quarters, 1 dollar/ 10 dimes

• 1 foot/12 inches

• 1.0 meters = ? Cm

• 12 DL = ? mL

• 155 dg = ? Kg

• Density is equal to mass divided by volume

• D = m/V

• Volume= l x w x h or liters

• If an object masses 114g and has the volume of 10.0 cm3 what is its density

• D=

• Mass- 3.1 g, Volume 0.35 cm3 D= ?

• Mass- 14 g, Density- 10.5 g/cm3 Volume= ?
