Quoted:
I have never been able to figure this out. The best thing I've heard so far is that you can divide both inches and feet by 2, 3 and 4, whereas I can only divide S.I. units by 2 and 5. Both are pretty much arbitrary, and you can always use decimal inches, decimal feet. Machinists use decimal inches and surveyor use decimal feet all the time. And even metric is generally screwed up by the users that think killogrqams is a weight. Weight is in Newtons. Mass id in kilograms. In the most common US system weight is in pounds and mass is in slugs. |

Why did you ask a question seeking input and then shit all over the input? Metric makes SOME math slightly easier. Not nearly enough to justify the absolutely insane cost it would be to convert from imperial, which is designed around being useful and intuitive as measures of things.

Like that most cars are metric.
If I eyeball the size wrench I need, say 10mm and it is slightly too small, get a 11mm. US measurement I would try a 3/8 and if it were slightly small do I go with 7/16 or 11/32. How do I quickly visualize which is bigger, 7/16 or 11/32? Much easier in metric, what is bigger, 10mm or 11mm? |

Half retarded meth heads that roof houses every single day do with imperial units in thier head, what you claim "falls apart". Your arguments are retarded. The EPA needs to know RFN if the refit at the plant is going to kill the endangered snowflake fish they just discovered in the river in the summer or they will shit down a construction site costing tens of thousands of dollars an hour whether working at full capacity or sitting there doing nothing. You have been given the increase in temperature that is acceptable to let the fish get enough oxygen, the average flow and volume of the river, and the average summer temperatures. Whip out your HP15C, calculate the power output of the reactor, amount wasted as heat, the additional heat from using the water as coolant, how much you need to pump in for cooling, the temperature as it is pumped back out into the river, how much that raises the temperature of the river, Then go back to what you were working on when you were interrupted, Which involves the properties of steel, concrete, earth, decay, distance, half life, storage capacities, etc. Let me know how those go in furlongs, cables, square poles, gills, stones, and slugs. We prefer inches, pounds, gallons, miles, F degrees, etc. because we grew up with them and that is how we think- it is like our native language. For everyday life changing over would be like that uncomfortable phase where you have leaned a foreign language and speak and read it, but are constantly translating in your mind what you are going to say, and what you have heard to your native language because you don’t think in it year, have never dreamed in it yet, etc. |

My degree in physics required me to work in both Imperial and SI units. Never had any problems calculating in either one. It's best to use whichever system your audience is most familiar with and is applicable.
If you really want to warp your mind, try figuring out how a 2x4 isn't really a 2x4 anymore, but was in the past. Even worse, go see some old construction with real 2x4s and they will look weird to you. |

Systems based on powers of 2 and 3 are more intuitive than systems based on powers of 10.
Draw a square on a piece of paper. Then draw lines to divide it into 10 equal area parts. It's a lot easier to divide it into halves, quarters, eights, sixteenths, or any power of two. Even twelfths is better. SI is better for science and engineering. But 95% of the population will never need to know how many decagrams of deionized water there are in a cubic decimeter. |

The Fahrenheit scale is objectively better for every day use as it gives a higher degree of precision to the range we work with most. Weather in most of the US fluctuates between 0 F and 100 F. That's 100 units with which to state the temperature. In Celsius, that ranges from -18 C to 38 C. That means they can only state average temperature with about half the precision of the our system AND need to go negative to do it. Also, for every high school physics teacher telling kids they need metric to work in STEM fields, there is a crusty Mechanical Engineering professor still giving all of his problems in slugs. |
