How to Convert Length Measurements
Basic Length Conversion Method
To convert from one unit of length to another, you need to know the conversion factor between the two units. A conversion factor is a numerical factor by which a quantity expressed in one unit is multiplied to convert it into another unit.
Steps for Conversion
- Identify the conversion factor: This is the number you will multiply your measurement by to convert it to another unit. For example, to convert from meters to centimeters, the conversion factor is 100 (since 1 meter = 100 centimeters).
- Multiply or divide by the conversion factor: Depending on whether you are converting to a larger or smaller unit, you will either multiply or divide your original measurement by the conversion factor.
- Multiply if you are converting to a smaller unit.
- Divide if you are converting to a larger unit.
Length Measurements Conversion Examples
Ex. 1: Converting Meters to Centimeters
Conversion factor: 1 meter = 100 centimeters
Calculation: Length in centimeters = Length in meters × 100
Ans.: 5 meters × 100 = 500 centimeters
Ex. 2: Converting Centimeters to Meters
Conversion factor: 100 centimeters = 1 meter
Calculation: Length in meters = Length in centimeters ÷ 100
Ans.: 250 centimeters÷100= 2.5 meters
Ex. 3: Converting Inches to Feet
Conversion factor: 1 foot = 12 inches
Calculation: Length in feet = Length in inches ÷ 12
Ans.: 36 inches ÷ 12 = 3 feet
Ex. 4: Converting Feet to Inches
Conversion factor: 1 foot = 12 inches
Calculation: Length in inches = Length in feet ×12
Ans.: 4 feet ×12 = 48 inches
Common Conversion Factors
- 1 kilometer = 1,000 meters
- 1 meter = 100 centimeters
- 1 centimeter = 10 millimeters
- 1 mile = 1,609.34 meters
- 1 yard = 3 feet
- 1 foot = 12 inches
- 1 inch = 2.54 centimeters

History of The Metric System
The metric system, a decimal-based system of measurement, was developed during the French Revolution to address the complexities and inconsistencies of various local systems. Here is a brief history:
Origins and Development:
- Pre-Revolutionary France: Before the metric system, France used a multitude of local measurement systems, leading to confusion and inefficiencies in trade and science.
- 1789-1799 (French Revolution): The National Assembly of France sought to standardize measurements to unify the country and facilitate commerce. They tasked the Academy of Sciences to develop a new system.
The Metric System is Born:
- 1790: The Academy of Sciences proposed a new measurement system based on natural phenomena. A commission including prominent scientists like Jean-Charles de Borda, Joseph-Louis Lagrange, Pierre-Simon Laplace, and others was formed.
- 1795: The metric system was officially adopted in France. It included units like the meter for length, the liter for volume, and the gram for mass, all based on the decimal system.
Key Features and Early Adoption:
- Standardization: The meter was defined as one ten-millionth of the distance from the North Pole to the Equator. A platinum-iridium meter bar was created as a standard.
- Universal Application: The metric system was designed to be universal and simple, with all units based on powers of ten.
- 1799: The metric system became law in France. The first metric standards, the meter, and kilogram prototypes, were deposited in the Archives de la République in Paris.
International Spread:
- 19th Century: The system gradually spread to other countries, albeit slowly. Countries like the Netherlands and Belgium adopted it early on.
- 1875 (Metre Convention): An international treaty was signed by 17 nations, establishing the International Bureau of Weights and Measures (BIPM) to maintain international standards.
Modern Developments:
- 20th Century: The metric system became more widespread, especially after the adoption of the International System of Units (SI) in 1960, which refined and expanded the original metric system.
- 1970s-Present: Most countries have adopted the metric system for most purposes, although a few, like the United States, use it alongside customary units.
The International System of Units (SI):
- 1960: The 11th General Conference on Weights and Measures (CGPM) adopted the SI, which includes seven base units: meter (length), kilogram (mass), second (time), ampere (electric current), kelvin (temperature), mole (amount of substance), and candela (luminous intensity).
- Ongoing Evolution: The definitions of these units have been refined over time, increasingly based on fundamental physical constants for greater precision.
Importance of The Metric System
A significant step toward achieving global uniformity in science, commerce, and daily life was the adoption of the metric system. It facilitated communication and trade.
It is a robust and adaptable system for the demands of today because it uses units based on tens and natural objects.
Length Conversion Table
