A Degree to Time Calculator converts angular degrees into time based on Earth's rotational movement. Since Earth rotates 360° in 24 hours, this conversion helps determine time differences based on longitude, which is crucial in astronomy, navigation, and time zone calculations.
Importance of Degree to Time Conversion:
- Essential in Astronomy: Helps calculate the movement of celestial objects across the sky.
- Used in Global Timekeeping: Converts degrees of longitude into time differences between locations.
- Vital for Navigation: Assists sailors, pilots, and travelers in understanding time shifts.
- Supports Geographical Studies: Helps in analyzing sunrise, sunset, and time zone differences.
Formula of Degree To Time Calculator
Since Earth completes 360° in 24 hours, the following relationships apply:
- 1° = 4 minutes (or 240 seconds)
- 15° = 1 hour
- 360° = 24 hours
Using these principles, the conversion formulas are:
- Hours = Degrees / 15
- Minutes = Degrees × 4
- Seconds = Degrees × 240
Degree to Time Reference Table
The table below provides common degree-to-time conversions:
| Degrees | Hours | Minutes | Seconds |
|---|---|---|---|
| 1° | 0.067 | 4 | 240 |
| 5° | 0.333 | 20 | 1,200 |
| 10° | 0.667 | 40 | 2,400 |
| 15° | 1.000 | 60 | 3,600 |
| 30° | 2.000 | 120 | 7,200 |
| 45° | 3.000 | 180 | 10,800 |
| 90° | 6.000 | 360 | 21,600 |
| 180° | 12.000 | 720 | 43,200 |
| 360° | 24.000 | 1,440 | 86,400 |
This table helps users quickly convert degrees to time for various applications.
Example of Degree To Time Calculator
Suppose you want to convert 75 degrees into time:
Step 1: Convert to hours
Hours = 75 / 15
Hours = 5 hours
Step 2: Convert to minutes
Minutes = 75 × 4
Minutes = 300 minutes
Step 3: Convert to seconds
Seconds = 75 × 240
Seconds = 18,000 seconds
Thus, 75 degrees corresponds to 5 hours, 300 minutes, or 18,000 seconds.
Most Common FAQs
Since Earth rotates 360° in 24 hours, dividing 360 by 24 gives 15° per hour.
Time zones are generally 15° apart, meaning every 15-degree shift in longitude corresponds to a 1-hour difference.
Yes, astronomers use similar principles to calculate time shifts on other rotating celestial bodies.
