Clearly shows that hours and minutes are messy units. The French Revolution fixed a lot of stupid problems, but decimal time just didn’t stick for some reason.
Cannot say why decimal time didn't stick, but a similarly-proposed semi-decimal calendar with 12 months of 3 weeks each of 10 days was abandoned in France solely because Napoleon didn't like it.
It was also designed to frustrate Sunday church attendance because Sundays being every seven days would usually fall on a weekday on a workweek based on a ten-day week. While Revolutionary France experimented with state atheism and then deism, it eventually returned to Catholicism.
France spread its decimal measurements (the metre, gram, and litre) to the countries that Napoleon conquered or tried to conquer, but by that time, France was well beyond the "stamp out all semblance of religion" phase of its revolution, so a calendar designed with the intent to stifle religious attendance in mind was never going to stick very long once the French had left those territories. Besides, doing maths on length, volume, and mass is something that people do far more often than performing those calculations on dates. Sure, it would have made some things more convenient, but I'm guessing that for most people, the ten-day weeks just stuck out like a sore thumb.
In normal everyday life, you rarely need to involve time in your calculations. In science and engineering you do, and that’s when you run into problems.
When comparing two pumps, you run into issues like this. Which one is bigger: 29 m^3/h or 410 l/min. Doing calculations like that once or twice is recreational mathematics, but in a professional setting, these conversions are speed bumps standing in the way of getting stuff done.
I've absolutely done it before because I'm weird. Entering 1:90 (on my Kenmore microwave) ticks down 1:89... 1:88... etc. until it hits 1:00 at which point it will continue as normal to 0:59.
1:60 behaves similarly.
I have a feeling the "add 30 seconds" button will correct it to proper time format, but I'll test it for science.
I didn’t realize I was so spoiled. On mine, the 1, 2, and 3 buttons add 1-3 minutes, respectively. And I don’t have to hit start either. I want a minute I press 1, done. 90 seconds would be 1 and +30, two button presses.
I'll only buy a microwave if it stops beeping when I open the door. So if I open it right as the timer finishes then it only does like half of one beep.
Side note, the microwave also needs to go straight to time entry once I start pressing numbers. I've seen some stupid microwaves that you need to press a Time Cook button before the numbers or it will assume you are using its preset cook settings like "pizza" or "soup".
Had a friend who got a microwave that instead of a numpad it had a dial like a volume knob. It was so irritating for some reason to twist it and then have to turn it the opposite way to correct it. Like you wanted 45 seconds and you'd twist and it's be at 1:30, youd scroll back, 35... 50, fuck it good enough. I just would twist it to a number and then stop it 45 seconds in after I realized it was that way
