First, convert the minute values into decimal values
| 214+(35×160) |
= |
214+(3560) |
|
|
= |
214+0.583 |
|
= |
214.583° |
Finally, use the formula to convert the degree to radians
| radian |
= |
degrees×π180° |
|
|
= |
214.583°×π180° |
|
|
= |
214.583°π180° |
|
|
= |
214.583×3.14159180 |
Use π=3.14159 |
|
|
= |
3.745 |
Rounded to three decimal places |

Use π=3.14159 |
|
|
= |
171.89° |
Rounded to two decimal places |
Finally, convert the decimal values into minute values
| 171+(0.89×601) |
= |
171°+(53′) |
|
|
= |
