Time Conversions
Values for time (in hours, H) or angles (in degrees, D) can be converted between a
decimal–fraction form (H.h or D.d) and a minutes–seconds form (H.MMSSss or
D.MMSSss) using the

or
º ³
keys.
To convert between decimal fractions and minutes–seconds:
1. Key in the time or angle (in decimal form or minutes–seconds form) that you
want to convert.
2. Press
