It could just as well be a shifted Fahrenheit scale and be just as good. Celsius vs Fahrenheit: none is really better, but I vote for Celsius cuz that's what I am used to. Kelvin is slightly better, and I wouldn't mind everyone using Kelvin. For casually talking about weather we would probably drop the 200/300 part because it would usually be obvious, and that's that. standard Made my day. Yes, i know, and that's why Celsius is better. If you want to convert from Fahrenheit to Kelvin quickly, the best option is to use your TI. IF Kelvin was Fahrenheit shifted, then it would be better, for the same reason that Celsius is better. If you ever study Transport Phenomena, you'll understand how bad the "Standard" system is. Specially when the teacher don't let you use a programmable calculator. | ||

Unfortunately, I also live in America, so I have to simultaneously teach kids to get confused about 12 of these and 5280 of those -.-' Also, I disagree with the OP when he says that standard goes more naturally with fractions. When you set up any multiples of 10, it's easier than anything from standard to cross out zeroes to reduce fractions. Also, your second advantage for standard is incorrect too... people still buy liters of drinks lol. We're more accustomed to seeing everything in standard (like mph, rather than km/h), because we live in America. I've tutored mathematics for a pretty long time, have a bachelors in it, have a masters in math education, and am going for my doctorate in math education at the moment... and I gotta say that metric overall outclasses standard measurements. This. Yes, I think in mL / liters when I buy drinks. I think in meters for everything that is linked to distance. I simply think there is no single advantage of the "standard" system. | ||

Turkey uses metric system so I'm pretty used to it. Things like feet, inch, ounce or pound just seem weird to me, I don't get the concept. For example, I checked some conversions for say, ounce, and it is listed as 28.349523125 g from the Wikipedia page. I mean...WTF. I can understand that if they are already measured and say, an ounce of milk is available in stores, that wouldn't confuse me as a citizen but...how is it measured exactly? I'm more curious in how the standard is agreed upon. Metric system is really easy to understand as the OP stated. The terms are related to each other, and tbh I've never seen people wanting to buy a dekameter of wood or something. It all goes according to meters. Things like 1.3 metres are okay to understand mathematically, so there is no need to memorize a ton of names for specific measurements. Also, this guy nails it.

Standard goes more naturally with fractions - quarter of a pint, half foot, etc. Technically, you don't say half meter but rather 50 centimeters or 500 millimeters. 2. Standard units are more practical and convenient. No one goes to the grocery to buy 400ml drink, instead, they buy it in 12 ounces. No one buys 5 meters of wood, instead, they buy it is 1x1x12, all in feet. What in the world am i reading? How are the things you use as an example any different? What a silly thread | ||

People really need to adapt and stop living in the dark ages. I remember one story of a building error caused by someone from one country using the metric system, transmitting his results to another person somewhere else who assumed they were in imperial units and managing to fuck something up. I think this was related to building a shuttle too if I recall correctly, so the people working on these things are supposed to be smart. I blame the first guy for not putting his units in but things like that should just never happen. It would be much simpler to teach a uniformed system to the entire world instead of having to adapt to ancient systems based on observation and not logic. Not a building error, but another example: CNN "NASA lost a 125 million Mars orbiter because a Lockheed Martin engineering team used English units of measurement while the agencys team used the more conventional metric system for a key spacecraft operation, according to a review finding released Thursday." http://articles.cnn.com/1999-09-30/tech/9909_30_mars.metric.02_1_climate-orbiter-spacecraft-team-metric-system?_s=PM:TECH | ||

Also, directed towards the first advantage of the American Imperial system in the OP, that's pretty silly. Half a litre is equivalent to 500 mL, and people will say both. We're basically using SI prefixes, so everything's interchangeable. Half a litre = 0.5 L = 500 mL = 5 cL = 0.0005 kL = 500 000 μL. I'm sure you get the point. The metric system also makes a lot more sense for measuring things on a wider scale. For example, how would you describe the wavelength of x-rays, or the distance between the Earth and say Jupiter in the American Imperial system? As far as I know, you can't. Or at least, not easily. Basically, when people say metric system, they mean that they use SI units, which are exactly defined. In comparison, how are inches or pounds defined? Are they even? (I'm actually curious, not just trying to make a point). | ||

I've been making an effort to use metric more and more for the last few years. I still prefer pounds for body weight, miles for distance, and pounds for body weight though. | ||

fluid ounces... totally confused me at an airport once... then i asked for half a liter, ended up pointing at a cup ;-) a fluid ounce is 28.4ml in the UK and 29.6ml in the US, not to confused with an ounce, which is 28.3gram or the troy ounce which is 31.2g... | ||
