Definition
Length is the measurement of something from one end to the other. It is typically the largest dimension of an object. For example, in a rectangle, the length is greater than the breadth. Length is a measure of distance in the International System of Quantities.
Units
Length is measured using standard units. The base unit of length in the International System of Units (SI) is the meter, represented by the symbol 'm'. Depending on the size of the object, other units such as kilometers (km), centimeters (cm), or millimeters (mm) are used. For example, the length of a bridge may be measured in kilometers, while a table might be measured in meters.
Length Conversion
Length can be converted between different units. In the metric system, conversions are often made between kilometers (km), meters (m), decimeters (dm), centimeters (cm), and millimeters (mm). For example, you can convert from kilometers to meters, or from meters to centimeters, using specific conversion formulas.
Length Conversion Table
km to m | m to cm | cm to mm |
---|
1 km = 1000 m | 1 m = 100 cm | 1 cm = 10 mm |
2 km = 2000 m | 2 m = 200 cm | 2 cm = 20 mm |
5 km = 5000 m | 10 m = 1000 cm | 10 cm = 100 mm |
10 km = 10000 m | 50 m = 5000 cm | 50 cm = 500 mm |
100 km = 100000 m | 100 m = 10000 cm | 100 cm = 1000 mm |
Length and Breadth
In geometry, length and breadth are often used to describe the dimensions of objects. For example, in a rectangle, the longer side is called the length, and the shorter side is the breadth. These dimensions are essential in calculating the perimeter and area of objects.
How to Measure Length?
Length can be measured using tools such as rulers or measuring tapes. A ruler is ideal for small objects, typically up to 30 cm, while a measuring tape is used for longer objects like walls or furniture. These tools allow for precise and quick measurement of objects, whether large or small.
Frequently Asked Questions (FAQ)
How can I convert meters to centimeters?
To convert meters to centimeters, simply multiply the number of meters by 100. For example, 2 meters is equal to 200 centimeters.
What is the base unit of length in the metric system?
The base unit of length in the metric system is the meter, abbreviated as 'm'.
Which tools are commonly used to measure length?
Common tools for measuring length include rulers, measuring tapes, and sometimes laser measuring devices for greater accuracy over long distances.
