----------- Time measures: 1000 ms = 1 sec 60 secs = 1 min 60 mins = 1 hour 24 hours = 1 day ----------- Temperature measures: 0º C = Water freezes (at 1 atm) 100º C = Water vaporizes (at 1 atm) ----------- Distance measures: 10^3 m = 1 km 10^2 m = 1 hm 10 m = 1 dam 1 m 10^-1 m = 1 dm 10^-2 m = 1 cm 10^-3 m = 1 mm :p | ||

Basing on history and structure, Id guess the hour system is imperial since 50 sec = 1 min, 60 min = 1 hr, 24 hr = 1 day, 7 days = 1 wk, 28/29/30/31 days = 1 month,12 mo = 1 year? I wonder how the metric system will handle with this? 100 mins to 1 hr? Has there been any suggestion to metricize time? Imperial is not the only non-metric system. Before introduction of metric system there was a lot of measurement systems that were not imperial. So no hour system is not imperial. And it also metric as unlike length and weight there are two unavoidable units : 1 day and 1 year. You need those two. | ||

So was there ever an attempt in history to measure time in base of 10, as the rest of the metric system operates? | ||

As for Metric Vs Imperial, there is no debate. Metric is simplier. There is nothing wrong with a simplier system. | ||

I'm impressed it's gathered this many pages of seemingly reasonable discussion. On January 11 2012 12:57 mcc wrote: Imperial is not the only non-metric system.

And it also metric as unlike length and weight there are two unavoidable units : 1 day and 1 year. You need those two. Just to clarify, the reason this is unavoidable and stops time being measured metrically is because the day and year are connected. You can't have a hundred day year, because it has to sync up with the earth's rotation around the sun. That combined with the innateness of time means it probably won't ever go metric. People would just get too badly messed up. The effort required from the entire population of the world to re-wire themselves to a hundred-minute hour, for example, would vastly outweigh any benefits of doing so. Plus, those benefits themselves are probably pretty negligible. As someone else said, the USSR tried 10 day weeks at one point and it caused all sorts of weirdness. Somehow, seven seems to be a really good (if numerically awkward) number. EDIT: and yes, obviously time isn't technically Imperial. I think in some places that have been metric for a while, certainly among the people I know, "Imperial" comes to be used for any measurement system that isn't in base ten, or which is seen to be a little archaic. | ||

Or the sun has app. 2x 10^30kg mass. Or 1 litre is 1 dm³ or 10x10x10cm in volume. You are immune to sarcasm, is that your superpower? | ||

I mean, since years/months and days are given by lunar cicle (more or less) and the earth's orbit and rotation you can't really do much there. And people have gotten used too much to hours/minutes/seconds in a base 24/60/60. I mean, you could change that. But dont forget that angles are also measured with 360 degrees, 1 degree is 60 minutes or 3600 seconds. | ||

The 1 lession he gave me was simple enough to understand, I still have a little trouble with it, but to be using imperial/standard for most of my life compared to 1 lession, it's very obvious how easy Metric is compared to Standard. To me, standard feels and looks simpler, but I know its not, its just because America hardly uses metric so you don't use it often, lol. It should definitely be used instead of Standard, but... they'd need to slowly integrate it otherwise people will go nuts. | ||

Anything related to schoolwork though is metric. If I get the problem in imperial units I will often convert them into metric. | ||

That may sound even more complicated, but actually, it is not, since it is actually the most natural way to measure an angle, and not some random measurement you put onto it. | ||

The calender predates Imperial and Metric systems, though (Russians please correct me on this if I am wrong) the Soviet Union experimented with ten days weeks but it didn't just work. As for Metric Vs Imperial, there is no debate. Metric is simplier. There is nothing wrong with a simplier system. No, they tried to change it to five days. : ) There wasn't really a problem with this system it was just a bit different and I suppose that's why they changed it back to seven days. | ||
