What Is the Metric Conversion Chart?

The Metric Conversion Chart is a tool that facilitates the conversion between various metric units of measurement. It often includes customary (imperial or US customary) units as well, making it easier to convert between these two measurement systems.

A metric system conversion chart typically includes unit conversions for measurements like length, mass, volume, temperature, and other common units. The chart provides a quick and convenient way to convert measurements from one unit to another by listing the conversion factors between each pair of units. This helps users easily perform conversions without complex calculations.

  • What Is the Metric System? 

The metric system is a widely used decimal-based measurement system that uses the base units meter (for length), liter (for volume or capacity), and gram (for mass or weight).

Note that the SI system (International System of Units) is often referred to as the modern form of metric system. 

  • What Is a Conversion Factor? 

A conversion factor is a numerical ratio used to convert between different units of measurement. It demonstrates how two units are related, facilitating the conversion from one to the other. For instance, since there are 100 centimeters in one meter, the conversion factor between meters (m) and centimeters (cm) is 100.

Simple Tricks to Remember Metric Conversions

Before we jump into metric units conversion, let’s learn a simple trick to remember these conversions easily.

Moving to RightIf you move n positions to the right from any place, multiply by 10n.• 1 meter = 10 decimeters
• 7 hectometer = 700 meters
• 5 km = 5000 meters

Moving to Left
If you move n positions to the left from any place, divide by 10n (or multiply by 10-n).• 1 meter = 0.1 decameter
• 2 cm = 0.02 m
• 43 mm = 0.043 m

Facts about Metric Conversion Chart

  • The metric system is decimal-based, meaning it uses powers of ten for conversion. This makes calculations and conversions easier as you’re moving the decimal point.
  • The United States uses a variation of the imperial system known as the US customary system. While similar, there are differences, such as in the size of fluid ounces and gallons.
  • The SI system, a modern standardized form of the metric system, is the widely used measurement system.

Conclusion

In this article, we learned about the intricacies and essential details of the metric system conversion tables for different measurements. To solidify our understanding and ensure mastery of these conversions, let’s solve a few examples and practice MCQs for better comprehension.

Solved Examples on Metric Conversion Chart

Example 1: Carry out the following metric conversions.

i) Convert 50 km into millimeters. 

ii) Convert 27 milliliters into liters.

iii) Convert 158 grams into kilograms.

Solution:

i) 1 km = 1,000,000 mm

50 km = $50 \times 1,000,000$ mm

50 km = $5 \times 10^{7}$ mm

50 km = 50,000,000 mm

ii) 1 L = 1000 mL

1 mL = 0.001 L

Thus, 27 mL = $27 \times 0.001$ L

27 mL = 0.027 L

iii) 1000 g = 1 kg 

158 g = $\frac{158}{1000}$ kg

158 g = 0.158 g

Example 2: A pole is 72 inches long. Find its length in cm.

Solution:

We know that 1 inch = 2.54 centimeters

Length of the pole = 72 inches

Multiply the given length by the conversion factor of 2.54.

Length in cm $= 72 \times 2.54$ feet

Length in cm = 182.88 cm

Therefore, the length of the pole is 182.88 cm.

Example 3: A bottle has a capacity of 20 mL. How many such bottles will fill up a bottle with a capacity of 1 liter?

Solution:

We know that 1000 mL = 1 L

To find out how many 20 mL bottles are needed to fill a 1 L bottle, you should divide 1000 mL by 20 mL:

$\frac{1000}{20}$ = 50

Therefore, 50 such 20 mL bottles will be required to fill up a bottle with a capacity of 1 liter.

Frequently Asked Questions about Metric Conversion Chart

The metric system is used globally because it is standardized based on the decimal system (number 10), making it easier to understand, use, and convert between units. It is the international system of measurement for most countries and scientific communities.

A liter is a unit of liquid volume equal to 0.001 cubic centimeters (cm³), while a cubic meter is a larger unit of volume that equals 1,000 liters. Essentially, a cubic meter is used for larger volumes, and a liter is more common for everyday use.

The International System of Units (SI) and the metric system are closely related, and the terms are often used interchangeably, however, the SI system provides a global standard for measurements and is considered as a more standardized and modern form of the metric system. It is regularly updated to reflect advancements in measurement science and technology.
