Metric units are units of measurement that use the international system of units (also known as the metric system). Common metric units include grams for mass, meters for length, and liters for volume.
Grams measure mass, which is the measurement of the amount of matter in an object. Grams are used to measure the amount of ingredients in a recipe or the mass of small objects.
Meters measure length, which is the measurement of how long something is. Meters are used to measure the height of a person or the length of a room.
Liters measure volume, which is the measurement of how much space an object takes up. Liters are used to measure the capacity of a water bottle or gas tank.
Kilograms measure mass, which is the measurement of the amount of matter in an object. Kilograms are usually used to measure the weight of large objects like cars or furniture.
Centimeters measure length, which is the measurement of how long something is. Centimeters are commonly used to measure the height of a person or the length of a ruler.
Milliliters measure volume, which is the measurement of how much space an object takes up. Milliliters are often used to measure the amount of liquid in a container or the capacity of a medicine bottle.
Hours measure time, which is the measurement of the passing of moments from the past to the future. Hours are used to measure the length of a movie or the amount of time spent on a task.
Miles measure distance, which is the measurement of the amount of space between two points. Miles are usually used to measure the distance between two cities or the length of a road.
Kilometers measure distance, which is the measurement of the amount of space between two points. Kilometers are often used to measure the distance between two countries or the length of a highway.
Gigabytes measure digital storage, which is the measurement of the amount of space available for storing digital information. Gigabytes are commonly used to measure the capacity of a hard drive or the amount of space available on a computer.
Kilowatt-hours measure energy, which is the measurement of the amount of work that can be done by a force. Kilowatt-hours are usually used to measure the amount of energy used by a device or the amount of electricity used by a home.
Hertz measure frequency, which is the measurement of how often something occurs. Hertz are commonly used to measure the number of times a machine vibrates or the number of cycles of a sound wave.
Celsius measure temperature, which is the measurement of how hot or cold something is. Celsius is usually used to measure the temperature of a room or the temperature of the air.
Atmospheres measure pressure, which is the measurement of the amount of force applied to an area. Atmospheres are often used to measure the pressure in a tire or the pressure in an air conditioning unit.
Metric units are the most widely used units of measurement in the world today. As the world increasingly adopts the metric system, it is important to become familiar with these common metric units. Knowing the common metric units will help you understand measurements of physical quantities, such as mass, length, volume, time, energy, and frequency.
