Metric Review

International System of Units (SI) Base of 10 1 meter = 100 centimeters=1000 millimeters Standard Units: -Mass = gram (g) -Length = meter (m) -Volume = liter (l) or cubic centimeter (cm3) All measurements have a number and a unit

Area The amount of surface within given boundaries A = length x width A = L x W Units = square centimeters (cm2)

Volume of Regular Solid Objects The amount of space an object “takes up” V = length x width x height V = L x W x H Units = cm3 (cubic centimeters)

Volume of Irregular Solid Objects Use the water displacement method in a graduated cylinder V = Final measurement – Initial measurement

Volume of Liquid Measured in a graduated cylinder Units = liters (L) 1 ml = 1 cm3

Mass The measure of the amount of matter in an object - Measured with a balance scale - Weight = the measure of the force of gravity on a mass - Measured with a spring scale Mass is not equal to weight

Density The amount of matter in a given volume D = MassD = m/vVD = m volume Units = g/cm3

Temperature Measured with thermometer SI unit for temperature = Celsius (C) - Celsius scale is based on the freezing and boiling points of water -Freezing = 0 degrees C -Boiling = 100 degrees C SI unit for extreme temperature = Kelvin

Temperature Conversions Fahrenheit to Celsius F = C (9/5) + 32 Celsius to Fahrenheit C = (F-32) (5/9) Celsius to Kelvin K=C-273.15 Kelvin to Celsius C = K+ 273.15
