Hour to minute conversions.

One of the tools I use at work is a stopwatch program I use to keep track of my break times. I also use the stopwatch’s countdown feature to count down the time remaining to those rare moments of freedom, such as my lunch break or the end of my shift. It can display this time remaining in either seconds, minutes or hours. I choose to have the countdown displayed in hours since the numbers change less frequently and are less distracting than the other formats. This does leave me trying to decipher numbers such as .585 or .666. I have to use the calculator program to convert that number into minutes to give me a better idea of how much time is left until lunch.

In helping me better interpret the hour equivalents of the countdown in progress I created an Excel spreadsheet in the form of a reference table to convert hours to minutes. I reprint the table here.

0.975 58.50 0.650 39.00 0.325 19.50
0.950 57.00 0.625 37.50 0.300 18.00
0.925 55.50 0.600 36.00 0.275 16.50
0.900 54.00 0.575 34.50 0.250 15.00
0.875 52.50 0.550 33.00 0.225 13.50
0.850 51.00 0.525 31.50 0.200 12.00
0.825 49.50 0.500 30.00 0.175 10.50
0.800 48.00 0.475 28.50 0.150 9.00
0.775 46.50 0.450 27.00 0.125 7.50
0.750 45.00 0.425 25.50 0.100 6.00
0.725 43.50 0.400 24.00 0.075 4.50
0.700 42.00 0.375 22.50 0.050 3.00
0.675 40.50 0.350 21.00 0.025 1.50

So if the display on the timer reads .975, it would mean 58 minutes and 30 seconds left in the countdown. Simple.

I know, this is the second consecutive blog post on countdowns.  Nothing wrong with helping people better anticipate the end of their shifts.
