^{th}century. This was done so that several systems of measurement, which were in use at that time found a unified and a universal platform. The primary motive behind this was to facilitate easier trade amongst various countries or regions, which used differing systems of measurement. The basis of this system was derived from nature itself. Water, for example, was used as one basis. 1 liter of water weighed 1 kg and measured 1 cubic decimeter. Water froze at zero degree Celsius, and boiled at hundred degree Celsius.

Provided below are a few metric units and conversions for your easy reference:

Metric Measurement System

*Length*

10 millimeters = 1 centimeter

10 centimeters = 1 decimeter

10 decimeter = 1 meterĀ

10 meters = 1 decameter

10 decameters = 1 hectometer

10 hectometers = 1 kilometer

1000 millimeters = 1 meter

100 centimeters = 1 meter

1000 meters = 1 kilometer

*Mass*

1000 grams = 1 kilogram

1000 kilograms = 1 ton

*Capacity*

10 milliliters = 1 centiliter

10 centiliters = 1 deciliter

10 deciliters = 1 liter

1000 milliliters = 1 liter

*Area*

100 square millimeters = 1 square centimeter

100 square meters = 1 acre

100 acres = 1 hectare

100 hectares = 1 square kilometer

10000 square centimeters = 1 square meter

10000 square meters = 1 hectare

1000000 square meters = 1 square kilometer

Imperial Measurements System

__Length__

12 inches = 1 foot

3 feet = 1 yard

22 yards = 1 chain

10 chains = 1 furlong

8 furlongs = 1 mile

5280 feet = 1 mile

1760 yards = 1 mile

*Mass*

437.5 grains = 1 ounce

16 ounces = 1 pound

14 pounds = 1 stone

8 stones = 1 hundredweight

20 hundredweights = 1 ton

*Capacity*

20 fluid ounces = 1 pint

4 gills = 1 pint

2 pints = 1 quart

4 quarts = 1 gallon

8 pints = 1 gallon

*Area*

144 square inches = 1 square foot

9 square feet = 1 square yard

4840 square yards = 1 acre

640 acres = 1 square mile

Conversion Formulae

*Length*

1 inch = 2.54 centimeters

1 foot = 0.3048 meters

1 mile = 1.6093 kilometers

1 centimeter = 0.3937 inch

1 meter = 3.2808 feet

1 kilometer = 0.62137 mile

*Mass*

1 ounce = 28.3495 grams

1 pound = 0.4536 kilograms

1 kilogram = 2.2046 pounds

1 gram = 0.0353 ounce

*Capacity*

1 gallon = 3.7853 liters

1 liter = 1.0567 quarts

*Area*

1 square foot = 929.0304 square centimeters

1 square meter = 1550.003 square inches

*From Fahrenheit to Celsius:*

Deduct 32 from the Fahrenheit temperature, multiply the result by 5m and then divide that result by 9 to get the Celsius temperature.

*From Celsius to Fahrenheit:*

Multiply the Celsius temperature by 9, divide the result by 5, and then add 32 to that result to get the Fahrenheit temperature.
