# Length calculator

The formula for converting one unit of length to another depends on the units being converted. Here are some of the most common conversions and their formulas:

1. Inches to centimeters: 1 inch = 2.54 centimeters
2. Feet to meters: 1 foot = 0.3048 meters
3. Yards to meters: 1 yard = 0.9144 meters
4. Miles to kilometers: 1 mile = 1.60934 kilometers
5. Meters to centimeters: 1 meter = 100 centimeters
6. Centimeters to millimeters: 1 centimeter = 10 millimeters
7. Kilometers to meters: 1 kilometer = 1000 meters
8. Nanometers to meters: 1 nanometer = 1.0 x 10^-9 meters
9. Micrometers to meters: 1 micrometer = 1.0 x 10^-6 meters
10. Angstroms to meters: 1 angstrom = 1.0 x 10^-10 meters

To convert from one unit to another, you simply multiply the value by the conversion factor. For example, to convert 10 inches to centimeters, you would multiply 10 by 2.54 to get 25.4 centimeters.

### Here are some common length formulas and their step-by-step solutions:

1. Formula to convert meters to centimeters: To convert meters to centimeters, multiply the number of meters by 100. For example, if you want to convert 2 meters to centimeters, the calculation would be: 2 meters * 100 = 200 centimeters.
2. Formula to convert centimeters to meters: To convert centimeters to meters, divide the number of centimeters by 100. For example, if you want to convert 150 centimeters to meters, the calculation would be: 150 centimeters / 100 = 1.5 meters.
3. Formula to find the perimeter of a rectangle: The perimeter of a rectangle can be found by adding the length and width of the rectangle, and then multiplying the result by 2. For example, if the length of a rectangle is 6 meters and the width is 4 meters, the perimeter would be: (6 + 4) * 2 = 20 meters.
4. Formula to find the area of a rectangle: The area of a rectangle can be found by multiplying the length and width of the rectangle. For example, if the length of a rectangle is 6 meters and the width is 4 meters, the area would be: 6 * 4 = 24 square meters.
5. Formula to find the circumference of a circle: The circumference of a circle can be found by multiplying the diameter of the circle by pi (3.14159). For example, if the diameter of a circle is 10 meters, the circumference would be: 10 meters * 3.14159 = 31.4159 meters.
6. Formula to find the area of a circle: The area of a circle can be found by multiplying the radius of the circle squared by pi (3.14159). For example, if the radius of a circle is 5 meters, the area would be: 5 meters * 5 meters * 3.14159 = 78.5398 square meters.
7. Formula to find the volume of a rectangular prism: The volume of a rectangular prism can be found by multiplying the length, width, and height of the prism. For example, if the length of a rectangular prism is 3 meters, the width is 4 meters, and the height is 5 meters, the volume would be: 3 meters * 4 meters * 5 meters = 60 cubic meters.
