METRIC UNITS

Mass � � The metric unit used to measure mass is grams. A gram is about the mass of a paper clip.

Distance � � � The standard metric unit for distance (length) is the meter. A mile is about 1609 meters. A meter is about half the height of a normal human.

Time � � Time in the metric system is measured the same all over the world. Minutes, seconds, weeks, months, etc. are used.

Temperature � � The metric system measures temperature in degrees Celsius. The boiling point of water is 100 degrees Celsius and the freezing point of water is 0 degrees Celsius.

Velocity � � � Velocity (speed) is measured in meters (distance) per second. m/s = meters per second Americans measure velocity in miles per hour.

Acceleration � � � Acceleration is the change in velocity over time. Acceleration is measured in meters per second squared. m/s 2

Density � � Density is mass divided by volume. D= m/v Density of a solid is measured in g/cm³. Density of a liquid is g/m. L.

Force � The SI (or metric) unit is the Newton, defined as the force needed to accelerate a mass of 1 kg at a rate of 1 meter/sec 2.

Energy � The Joule is the basic unit of energy in the metric system.

Power � The basic metric unit for electrical power measurement is the watt, which is equal to one joule per second.
