Angle Conversion Formulas
Angle conversion between different units uses these fundamental formulas:
Degrees to Radians
Radians = Degrees × (π / 180)
Radians to Degrees
Degrees = Radians × (180 / π)
Degrees to Gradians
Gradians = Degrees × (10 / 9)
Gradians to Degrees
Degrees = Gradians × (9 / 10)
Note: π (pi) is approximately 3.141592653589793. For more precise calculations, use the value of π provided by your calculation software.
Common Angle Conversions
Here are some common angle conversions you might encounter:
| Degrees | Radians | Gradians |
|---|---|---|
| 0° | 0 rad | 0 grad |
| 30° | 0.5236 rad | 33.3333 grad |
| 45° | 0.7854 rad | 50 grad |
| 60° | 1.0472 rad | 66.6667 grad |
| 90° | 1.5708 rad | 100 grad |
| 180° | 3.1416 rad | 200 grad |
| 270° | 4.7124 rad | 300 grad |
| 360° | 6.2832 rad | 400 grad |
This table provides quick reference points for common angle conversions. You can use these values as a guide when working with different angle measurement systems.
Angle Conversion Examples
Let's look at some practical examples of angle conversions:
Example 1: Converting 90 Degrees to Radians
Using the formula: Radians = Degrees × (π / 180)
90° × (3.1416 / 180) ≈ 1.5708 radians
So, 90 degrees is approximately 1.5708 radians.
Example 2: Converting 2 Radians to Degrees
Using the formula: Degrees = Radians × (180 / π)
2 × (180 / 3.1416) ≈ 114.5916 degrees
So, 2 radians is approximately 114.5916 degrees.
Example 3: Converting 100 Gradians to Degrees
Using the formula: Degrees = Gradians × (9 / 10)
100 × (9 / 10) = 90 degrees
So, 100 gradians is exactly 90 degrees.
These examples demonstrate how to convert between different angle units using the appropriate formulas. The calculator can handle these conversions quickly and accurately for any angle value you need to convert.
Frequently Asked Questions
What is the difference between degrees, radians, and gradians?
Degrees, radians, and gradians are all units of measurement for angles. Degrees are the most commonly used unit, with a full circle being 360 degrees. Radians are based on the radius of a circle, with a full circle being 2π radians (approximately 6.2832 radians). Gradians, also known as grads, divide a right angle into 100 parts, making a full circle 400 gradians.
When should I use degrees, radians, or gradians?
Degrees are typically used in everyday applications like navigation and construction. Radians are commonly used in advanced mathematics, physics, and engineering, especially when working with trigonometric functions. Gradians are less common but can be useful in certain technical applications where a different scale is preferred.
How accurate are the conversions in this calculator?
The calculator uses precise mathematical formulas to perform conversions. For most practical purposes, the results are accurate to several decimal places. However, for extremely precise calculations, you might want to use more advanced software or programming tools.
Can I convert angles to other units besides degrees, radians, and gradians?
This calculator specifically converts between degrees, radians, and gradians. If you need to convert to other angle units, you may need to use additional conversion tools or formulas.
Is there a way to save my angle conversion results?
Currently, this calculator does not have a save feature. However, you can manually note down the results or use your browser's print function to save a copy of the conversion.
