Everything else I could care less, there's no difference in any if it, just different sticks.

Decimals is currently the only way to measure with ease unless you grew up with imperial measurements as a tradition. 15/16ts of an inch vs 7/8s.. That is unless you know your customers are bound to get it wrong if they try the DIY route ![wink wink](/forum/images/graemlins/default/wink.gif) Come now, throw the rest of the imperial rule away. You have had sine 1781 to get this straight I can fully sympathize with Karl. 1/16ths of an inch are as common as counting or saying your ABCs, to someone who uses it 8-10 hours a day. And God help me if i have to use a tape with the fractions written on it. I've started using metric for boat stuff because it's more the norm in the A class (and F-18 apparently), but I'd go poor trying to do it at work everday.

I'm not sure about the kind of guys you've got working in the lumber yards in Arizona , but the ones around here would short circuit and explode if they had to learn metric. Half the the time they're lucky to get the boards within 2' lengths( that's .6096 of a meter,for you imperial challenged folks)of what you order loaded on the truck. If we were to switch over tomorrow I'd be OK with it , it would just take some serious mental recalibration.I'd probably survive.

It would be a big task to switch from metric to imperial here if situations were reversed. It would probably cause mental meltdowns and blown fuses plus all kind of production slowdowns. I personally would positively hate it. I always struggle when I am building to US plans with imperial measurements.. Perhaps the process could start with the schools and teachers. The rest would follow from there.. I know that MIT and other institutions have professors and lecturers insisting on SI units in all coursework. | | | Re: Knots vs. Miles

The problem is that darn near every piece of manufacturing equipment in the US uses inches and feet. Every road sign is in miles. It's an expensive switch to make but it would be nice to see us start using both to make the transition. We have some manufacturing overseas and a lot of international customers so we have supported both measurement systems in our manufacturing environment for years. Our component drawings show both measurement systems on every dimension.

Posts: 571 Hamburg | Which is all very logical and pre-GPS oriented. I think the world have moved on ![smile smile](/forum/images/graemlins/default/smile.gif) Yes logical and still used inside the GPS devices ![wink wink](/forum/images/graemlins/default/wink.gif) SI units is a good idea, however they selected the wrong base measures (what is the meaning of 1m, I guess some old french length measure). If 1 m would be 1.825m, I guess the whole word would have already converged to the SI system. So we will always measure distance in nm and speed in kts as long the earth turns because it is logic. | | |
