Brighterly is dedicated to providing interactive resources and kid-friendly content to make learning fun and engaging.

What is the Metric System?

The Metric System is a decimal-based system of measurement extensively used in science, industry, and daily life. This system comprises fundamental units like the meter (for length), kilogram (for mass), and second (for time), along with derived units such as pascal (for pressure), joule (for energy), and watt (for power). The system’s core principle is its reliance on the decimal system, which facilitates conversion and calculation by using powers of ten. This universality and simplicity make the Metric System an essential tool in mathematics, especially in fields requiring precise measurement and standardization.

Metric Units

The metric system has seven base units that serve as the foundation for all other units of measurement. These are:

  1. Meter (m) – length
  2. Kilogram (kg) – mass
  3. Second (s) – time
  4. Ampere (A) – electric current
  5. Kelvin (K) – temperature
  6. Mole (mol) – amount of substance
  7. Candela (cd) – luminous intensity

These base units can be combined with prefixes to create larger or smaller units. Some common prefixes include:

  • Kilo (k) – 1,000
  • Hecto (h) – 100
  • Deca (da) – 10
  • Deci (d) – 0.1
  • Centi (c) – 0.01
  • Milli (m) – 0.001
  • Micro (µ) – 0.000001
  • Nano (n) – 0.000000001

Metric System Chart

A metric system chart is a helpful tool for understanding the relationships between different metric units. It can be a table, diagram, or infographic that visually represents the metric units, their prefixes, and their values. A well-designed metric system chart can make it easier for children to grasp the concept of metric measurements and conversions. Here’s a sample metric system chart to help you visualize the relationships between different units.

Metric System Conversion

Converting between metric units is simple, as it only requires multiplying or dividing by powers of ten. This process is called metric system conversion. For example, to convert from kilometers to meters, you multiply by 1,000. To convert from centimeters to meters, you divide by 100. These conversions are essential for various real-life applications, such as calculating distances, weights, and temperatures.

Metric System Length

The base unit of length in the metric system is the meter (m). It is used to measure distances and sizes of objects. To express larger or smaller distances, we use prefixes like kilometers (km), centimeters (cm), and millimeters (mm). Here are some examples:

  • 1 kilometer (km) = 1,000 meters (m)
  • 1 meter (m) = 100 centimeters (cm)
  • 1 meter (m) = 1,000 millimeters (mm)

Metric System vs Imperial

The Imperial system is an older system of measurement that uses units such as inches, feet, yards, and miles for length, and ounces, pounds, and stones for weight. It is still widely used in the United States and a few other countries. Comparing the metric system to the Imperial system, we find that the metric system is much more straightforward and easier to learn, especially for children. The metric system’s base-ten structure simplifies conversions, while the Imperial system involves various conversion factors that can be challenging to memorize.

Solved Examples on Metric System

At Brighterly, we provide the best math worksheets for kids, helping them practice the metric system with ease. Here are some solved examples to help children understand metric system conversions:

  1. Convert 5 kilometers to meters:

    5 km × 1,000 = 5,000 meters

  2. Convert 120 centimeters to meters:

    120 cm ÷ 100 = 1.2 meters

  3. Convert 7,500 millimeters to meters:

    7,500 mm ÷ 1,000 = 7.5 meters
