## Metric and Imperial System

Imperial units, sometimes referred to as the British Imperial System is the standard system of weights and measures officially used in Great Britain from 1824 until the metric system was introduced in 1965. The Customary System of weights and measures of the United States is derived from the British Imperial System. International System of Units(abbreviated to SI) is the latest international standard metric system. Since the 1790s, as science and technology have progressed, metric systems have evolved to include a single standardized measurement device.

### Why we Need a Metric Conversion Chart Table?

Except for Myanmar, Liberia and the United States of America (USA) all the countries in the world uses the metric system as the primary measurement system. India, China, European countries, Russia all uses metric system whereas the USA still uses the Imperial system as the primary measurement system. There are some countries like United Kindom which uses both the Metric and Imperial system.

Since the USA hosts the most prestigious universities in the world. It is necessary for students to understand both systems of measurement. Also, it is important to know the conversion of Imperial weight to metric and vice versa.

Students should be familiar with the metric conversion chart table which gives the fundamental unit conversion between the Metric and Imperial systems. Also, most of the time Imperial to Metric conversion formula will be used for derived units.

### Imperial to Metric Conversion Formula

There are some units like tempurature which need the formula to convert the Imperial system to the metric system and vice versa. Celsius and Kelvin are units of temperature measurement in the Metric system whereas Fahrenheit is the unit of temperature measurement in the Imperial system.

The Imperial to Metric Conversion Formula for temperature is as follows:

Fahrenheit to Celsius

oF = 1.8oC + 32

Celsius to Fahrenheit

oC = (oF - 32)/1.8

Kelvin to Celcius

K = oC + 273

### Problems on Metric And Imperial Conversions

1) Convert 50 inches to meters.

Ans: 1 inch is equal to 0.0254 m. Therefore 50 inch will be equal to 50 * 0.0254 = 1.27 m.

2) Convert 20 meters to the yard.

Ans: We know that 1 yard is equal to 0.9144 m. So, 1 meter will be equal to 1/0.9144= 1.09361.

Therefore 20 meters will be equal to 20*1.09361=21.8723.

3) Convert 20 ounces to Kilograms.

Ans: From the Metric conversion chart table we know that 1 ounce equal 0.02835 Kg. Therefore 20 ounces will be equal to 20 * 0.02835 = 0.567 Kg.

4) Convert 80oF to oC.

Ans: We have a formula to convert Fahrenheit to Celsius.

oC = (oF - 32)/1.8

oC = (80 - 32)/1.8

oC = 48/1.8

oC = 26.67

So 80oF is equal to 26.67oC.

5) Convert 300oC to oF.

Ans: The formula to convert Celsius to Fahrenheit is as follows:

oF = 1.8oC + 32

oF = 300oC + 32

oF = 332

So 300oC to 332oF.

### Conclusion

For many factors, the metric system is the preferred scientific unit system.

The metric method of measurement is used by most countries in the world.

They are easily converted by shifting the decimal point since metric units are decimal-based.

The metric system is designed to make it easy to perform and understand measurements and calculations, which is one of the key reasons scientists use it.
