Conversion of the latitude of Paris (48º51’44”Nord) into decimal degrees:
48 [º ’’’] 51 [º ’’’] 44 [º ’’’] [=]
-> 48º51º44º
| 48º51º44.
[SHIFT] [ ]
-> 48º51º44º
| 48.86222222
Conversion of 123.678 into sexagesimal degrees:
123.678 [=] [SHIFT] [ ]
-> 123.678
| 123º 40º40.8
Time calculations
The sexagesimal conversion function can also be used for direct calculations
of hours / minutes/ seconds:
E.g.:
3hrs 30 mins 45sec + 6h 45mins 36sec
3 [º ’’’] 30 [º ’’’] 45 [º ’’’] [+] 6 [º ’’’] 45 [º ’’’] 36[º ’’’] [=]
-> 3º30º45+6º45º36 | 10º16º21.
thus 10hrs 16 mins 21 seconds.
3hrs 45 mins – 1,69hrs =
3 [º ’’’] 45 [º ’’’] – 1[.] 69 [=]
-> 3º45º – 1.69
| 2.06
[SHIFT] [ ]
3º45º – 1.69
| 2º3º36.
thus 2hrs 03mins et 36 seconds.

With the sexagesimal degrees (in degree mode):
sin (62º12’24”)=
[sin] 62 [º ’’’] 12 [º ’’’] 24 [º ’’’] [=] -> sin 62º12º24 | 0.884635235
