__Metric system/Si/ English system of measurement__

The International System of Units (SI)

More modern form of the metric system

This determines the base units for measurement

The English System

Based off of human features

Flawed

Only three countries besides the U.S. uses this

Units of Measurements

Metric system (SI)

English system

Mass

Gram

none

Length

Meter

none

Liquid

Liter

none

Weight

Neutron

Pound

Temperature

Celsius

Fahrenheit

Time

Second

Second

__Weight v.s Mass__

Weight

The pull of gravity on an object

The weight of an object changes depending on where it is located

So not so great of a measurement

Mass

The measurement of the number of atoms in an object

The mass of an object stays consistent no matter the location

A great measurement

__Volume and Density__

**Volume**The amount of space an object takes up

Formula (Solids): Base*Width*Height

Liquid Units | Solid Units |
---|---|

Liter | Cm |

Pint | M |

Quart | Ft |

Cup | Yd |

Mi |

Key Idea

Mass and volume are different

Large objects may have a small mass and vice versa

Always read Beakers at the lowest point of the liquid

1 cm

_{3}is equal to 1 mL

**Density**The measurement of the amount of matter in a defined amount of space

Units:

Solid g/cm

_{3}Liquid: g/mL

Density Formula is Mass/Volume

The density of water is 1 g/mL

If object is denser it will sink

If object is lighter it will float
