Angle Conversion Formula:
From: | To: |
Definition: This calculator converts angles from degrees and minutes format to decimal degrees for use in trigonometric calculations.
Purpose: It helps in precise angle measurements for navigation, surveying, astronomy, and engineering calculations.
The calculator uses the formula:
Where:
Explanation: The minutes are converted to a fraction of a degree by dividing by 60, then added to the whole degrees.
Details: Most trigonometric functions in calculators and programming languages require angles in decimal degrees rather than degrees-minutes format.
Tips: Enter the degrees (0-359) and minutes (0-59). The calculator will output the equivalent decimal degrees.
Q1: Why convert to decimal degrees?
A: Decimal degrees are easier to use in mathematical calculations and computer applications.
Q2: How precise is this conversion?
A: The conversion is mathematically exact, though displayed to 6 decimal places for practical use.
Q3: What about seconds?
A: For higher precision, seconds can be converted by dividing by 3600 and adding to the total.
Q4: Can I convert negative angles?
A: Yes, for negative angles (e.g., latitude south of equator), enter negative degrees.
Q5: How is this used in triangle calculations?
A: Decimal degrees are needed for trigonometric functions like sine, cosine in triangle solutions.
