Metric units are a standardized system of measurement used around the world, known as the metric system. It is based on powers of ten, making it easier to convert between units. The metric system includes units for measuring length, mass, volume, and temperature, among others.
For example:
- Length: The meter (m) is the base unit of length. A common example is that a standard door is about 2 meters tall.
- Mass: The kilogram (kg) is the base unit of mass. An example would be a bag of sugar that typically weighs 1 kilogram.
- Volume: The liter (L) is the unit used for measuring volume. A common example is a water bottle that holds 1 liter of water.
- Temperature: The degree Celsius (°C) is used for temperature measurement. For instance, water freezes at 0 °C and boils at 100 °C.
Overall, the metric system provides a universal framework for measurement, facilitating communication and understanding in science, trade, and daily life.
