Free Angle Converter Online

Angle conversion is a common task in mathematics and engineering, and an angle converter is a tool that makes it easy to convert between different units of angle. In this article, we'll explore what an angle converter is, how to use it, and why it's useful.

What is an Angle Converter?

An angle converter is a calculator or tool that allows you to convert between different units of angle. It can be used to convert degrees to radians, minutes of arc, seconds of arc, and more. Additionally, an angle converter can convert decimal degrees to degrees, minutes, and seconds, and vice versa.

Units of Angle

Before we dive into how to use an angle converter, let's first define some of the common units of angle.

• Degree (°): A degree is the most common unit of angle measurement. A full circle contains 360 degrees.
• Radian (rad): A radian is the angle subtended at the center of a circle by an arc equal in length to the radius of the circle. One radian is equal to approximately 57.3 degrees.
• Minute ('): A minute is a unit of angular measurement equal to one-sixtieth of a degree or one minute of arc.
• Second ("): A second is a unit of angular measurement equal to one-sixtieth of a minute of arc or one-three-thousand-six-hundredth of a degree.
• Decimal Degree (DD): A decimal degree is a decimal representation of degrees, where fractions of a degree are expressed as decimal parts.

How to Use an Angle Converter

Using an angle converter is easy. First, you need to select the input unit of angle and enter the value you want to convert. Next, you need to select the output unit of angle, and the converter will provide the converted value.

For example, let's say you want to convert 45 degrees to radians. You would enter 45 in the degree field and select radians as the output unit. The angle converter will give you the value of 0.7854 radians.

Decimal Degrees to Degrees, Minutes, and Seconds

Decimal degrees can be converted to degrees, minutes, and seconds by dividing the decimal value by 1.0, then multiplying the resulting fraction by 60 to get the number of minutes. The decimal value of the remaining fraction can then be multiplied by 60 to get the number of seconds.

For example, let's say you have a decimal degree value of 45.78333. To convert this to degrees, minutes, and seconds, you would first divide 45.78333 by 1.0, which gives you 45 degrees. Next, you would multiply the remaining fraction (0.78333) by 60 to get the number of minutes, which is 46. Finally, you would multiply the remaining fraction of the minutes (0.98) by 60 to get the number of seconds, which is 47.

Degrees to Radians 

To convert degrees to radians, you can use the following formula: Radians = Degrees x (π/180)

For example, to convert 45 degrees to radians, you would multiply 45 by π/180, which gives you

Radians = 0.7854
