MeasurementMeasurement

The International System of The International System of Units (Units (SISI) is the standard ) is the standard system used around the system used around the

world.world.

LengthLength

The standard SI unit to measure The standard SI unit to measure length is the meter (m).length is the meter (m).

The meter is divided into 100 equal The meter is divided into 100 equal parts called centimeters (cm).parts called centimeters (cm).

The centimeter is divided into 10 The centimeter is divided into 10 equal parts called millimeters (mm).equal parts called millimeters (mm).

Long distances are measured in Long distances are measured in kilometers (km) which is 1,000 m.kilometers (km) which is 1,000 m.

MassMass

Mass is the amount of matter that Mass is the amount of matter that something is made of.something is made of.

The kilogram is the SI unit to The kilogram is the SI unit to measure mass.measure mass.

Mass is measured with a triple Mass is measured with a triple balance beam.balance beam.

Unlike weight, mass does not change Unlike weight, mass does not change with an object’s position.with an object’s position.

WeightWeight

Weight is a measurement of the Weight is a measurement of the gravitational force on an object.gravitational force on an object.

The SI unit for force is the Newton (N).The SI unit for force is the Newton (N). Since weight is a measure of Since weight is a measure of

gravitational force, it does matter where gravitational force, it does matter where you are.you are.

There is 6 times less gravitational force There is 6 times less gravitational force on the moon, so you would weight 6 on the moon, so you would weight 6 times less there.times less there.

Use spring scales to measure weight.Use spring scales to measure weight.

DensityDensity

Density is mass per unit volume.Density is mass per unit volume. Density is the amount of matter it has Density is the amount of matter it has

in a given space.in a given space. To find density (D), first measure the To find density (D), first measure the

mass (m) and volume (V), then divide mass (m) and volume (V), then divide mass by volume.mass by volume.

Density is an SI derived unit Density is an SI derived unit (mass and (mass and volume) volume)

VolumeVolume Volume is the amount of space that Volume is the amount of space that

something occupies.something occupies. Volumes of liquids are expressed as liters Volumes of liquids are expressed as liters

(L).(L). Graduated cylinders are used to measure Graduated cylinders are used to measure

liquid volume, and also to find the volume of liquid volume, and also to find the volume of a small odd shaped object. (see meniscus)a small odd shaped object. (see meniscus)

Volumes of solid objects are expressed in Volumes of solid objects are expressed in cubic meters (cm3)cubic meters (cm3)

MeasurementMeasurementArea and VolumeArea and Volume

Area is the amount of surface Area is the amount of surface included within a set of boundaries included within a set of boundaries and is expressed in square such as and is expressed in square such as square meters (msquare meters (m22).).

The amount of space occupied by an The amount of space occupied by an object is the object’s volume. object is the object’s volume.

The basic SI unit of volume for a The basic SI unit of volume for a solid object is the cubic meter (msolid object is the cubic meter (m33).).

SI measurements for liquid SI measurements for liquid volumes are in milliliters (mL) or volumes are in milliliters (mL) or liters (L).liters (L).

TemperatureTemperature Temperature is a measure of the Temperature is a measure of the

average kinetic energy of the particles average kinetic energy of the particles in an object.in an object.

Temperature is not determined by how Temperature is not determined by how much of the substance you have.much of the substance you have.

The SI unit for temperature is Kelvin (K), The SI unit for temperature is Kelvin (K), however the Celsius (C) scale is most however the Celsius (C) scale is most commonly used.commonly used.
