Today hobbyists and even unskilled people can easily achieve millimetric precision using the modern tools we have. --- Quote from: coppercone2 on January 01, 2020, 12:35:35 am --- --- Quote from: Tepe on January 01, 2020, 12:31:42 am ---Billions of people cope just fine with centimeters and millimeters without being cyborgs. --- End quote --- they cope yes --- End quote --- You'll have to excuse those who apparently do not have English as their first language. What is meant is that billions of people do very well with centimeters and millimeters to their own advantage. |

I like the Fahrenheit scale better. 0 degrees F = really cold, and 100 degrees F = really hot while 0 degrees C = just chilly, and 100 degrees C = death! And an adult male can easily estimate a length in feet just by walking with one foot directly in front of the other (logically enough!). |

I grew up with degrees Celsius and meters, hence am used to these units and have developed a "gut feel" for them. Either of us feels more comfortable with the units we grew up with, and feel that they are "more natural", "more logical", or whatever. I am surprised that this bears repeating for 39 pages of forum thread, and counting... ::) |

Tooki: --- Quote ---It's just the metricness of it he's referring to. American tailors use the same kind of tapes, except that they've got metric on one side and inches on the other. ;) --- End quote --- Actually, it's the small size of the cm necessitating that the cumulatively running numbers have to be placed sideways on a metric tape measure. Virtually all metric tape measures run 1-10, only, because of the spacing issue. Virtually all imperial tape measures have cumulative numbers on every inch mark, and they don't have to be labelled sideways. --- Quote from: bsfeechannel on January 02, 2020, 07:35:14 am --- --- Quote from: KL27x on December 25, 2019, 02:35:38 am ---Naturally. Please inform bsfeechannel of this. He thinks the speed of light is based on the meter. --- End quote --- I don't mind that your posts be rife with fallacies, misconceptions and sheer ignorance. --- End quote --- I am not going to quote your entire post, because it was redundant the first time around, Captain Obvious. The speed of light is in meters per second to you. But in America we realize that the speed of light is ALSO 983,571,088 ft/s 1.08085305 E10 inches/s 704,227,509 miles per hour 582,856,941 knots In another 50 years you might figure this out. :palm: --- Quote ---The metric system reflects the advancements in precision by the manufacturing processes in the last two centuries.

Have you ever made machine parts out of steel? I have made tooling and parts to the nearest half a thous. That's about 1/80th of your millimeter. Building furniture, perhaps within the nearest mm is useful. But in any place you build furniture or cabinets you will usually joint and plane all your wood down to the same thickness within say 5 thous. And you will cut matching/symmetrical parts to match by using a using a stop block or cutting them at the same time. Which in furniture size wood, you should be able to repeat cuts to within 5-10 thous. You can convert that to metric, if you like. I'm sure you would think of these kinds of things in metric (if you actually built things like this). Framing a house, OTOH, the nearest eight an inch is all you will care, and a mm would be stupid small. IOW, the precision to which you make something has nothing to do with the units you choose to use. But it does have an effect on the numbers you end up working with and to. In America we use whichever is easier for the job, whether that's "millimetric precision LOL" or otherwise. |
