The Angle Between Bearings Calculator is a useful tool for determining the angle between two bearings. Bearings are commonly used in navigation, surveying, and engineering to indicate direction or position relative to a reference point. The angle between two bearings is important in many fields, such as navigation, where precise measurements of angles are critical for direction finding. This calculator uses a simple formula to provide an accurate result.
Formula
The formula used to calculate the angle between two bearings (θ) is:
θ = |(B2 − B1 + 360) % 360|
Where:
- B1 is the first bearing.
- B2 is the second bearing.
- θ is the angle between the two bearings.
This formula calculates the absolute value of the difference between the two bearings, adjusting for any values that exceed 360 degrees by adding 360 and taking the modulus with 360.
How to Use
- Enter the value of the first bearing (B1) in degrees.
- Enter the value of the second bearing (B2) in degrees.
- Click the “Calculate” button to find the angle between the bearings.
- The result will appear in the output field labeled “Angle Between Bearings (θ)”.
Example
Suppose you are working with two bearings:
- Bearing 1 (B1): 45 degrees
- Bearing 2 (B2): 120 degrees
The angle between the bearings can be calculated as follows:
θ = |(120 − 45 + 360) % 360|
θ = |75 + 360 % 360|
θ = |75 % 360|
θ = 75 degrees
Thus, the angle between the bearings is 75 degrees.
FAQs
- What is the Angle Between Bearings Calculator used for?
