Introduction
This document pertains to Time Conversions using the HP 32sii calculator.
Calculator symbol key
The procedures in this document use the following text to represent symbol keys:
 Key Description Text Representation Right shift key RS Left-shift key LS
Time conversions
Values for time (in hours, H), or angles (in degrees, D) can be converted between a decimal form (H.h or D.d) and a minutes-seconds form (H.MMSSss or D.MMSSss) using the LS, then HR or RS, then HMS keys
To convert between decimal fractions and minutes-seconds:
1. Key in the time or angle (in decimal form or minutes-seconds form) that will be converted.
2. Press RS, then HMS or LS, then HR. The result is displayed.
Example of converting time formats
How many minutes and seconds are there in 1/7 of an hour? Use FIX 6 display format.
 Keys Display Description Press LS, DISP, FX, then 6 Sets FIX 6 display format Press [.], 1, [.]. then 7 0 1/7_ 1/7 as a decimal fraction Press RS, then HMS 0.083429 Equals 8 minutes and 34.29 seconds Press LS, DISP, FX, then 4 0.0834 Restores FIX 4 display format
Angle conversions
When converting to radians, the number in the X-register is assumed to be degrees; when converting to degrees, the number in the X-register is assumed to be radians.
To convert an angle between degrees and radians
1. Key in the angle (in decimal degrees or radians) that will be converted.
2. Press RS, then RAD or LS, then DEG. The result will be displayed.
