When the longest one they made was 16' and it was still good economics to replace the tape blades. Once they went plastic, it was easier to buy the whole guts (spring and tape in a cartridge), now I just toss them. I do keep the tape if it is pristine to replace one that somebody steps on or nicks with a blade or snips.
It is. You just need to re-boot your brain and forget everything you knew about measurement units except TEN. How many mm in a Km?
1000000. just 1000 in a meter and 1000 meters in a Km. Try that with inches in a mile.How many conversion factors do you need to know?
12 inches in a foot, and 5280 feet in a mile, for 63360 inches per mile. Now, how many Cm in a Km? move the decimal point and you have 100000. How many yard in a mile? 1760. How many meters in a Km? Move the decimal point - 1000. How many rods in a mile? or chains? or furlongs?Then you go to area. How many square meters in a Hectare? 1000000 (1000 X 1000 = 1 sq Km) How many square yards in a square mile? (section) (1760X1760=) 3097600 How many square yards in an acre? 4840 How many acres in a section? 640
Then you go to weight.
How many grams in a tonne? A tonne is 1000 Kg - so 1000 X 1000 again. Grams in a Kg? - 1000. Oz in a pound? 16 lbs in a ton? 2000 Oz in a ton? 2000X16 = 32000 Unless you are talking precious metals or pharmaceuticals.
Liquid measure? How many ml in a liter? 1000 Compared to how many oz in a quart (which one?) or cup, or pint. And how many cupc in a pint, or quart, or gallon???
Yes, the metric system IS simple.
And easier to be more accurate. 1mm is just less than .039" .5mm is like .017, more or less, and .1mm is .0039, so .01mm os .0004, rounded up. - and you Americans measure in fractions instead of decimals. The smallest common measurement is the 64th of an inch - about .016" - or .4mm
Multiply that by 5, for 5/64 - or multiply .4mm by 5 and get 2mm.
Which is simplest???????
You got me Han. Moved the decimal point one too far. MM to CM is 1 point. (factor of 10) CM to M is 2 points (factor of
100) M to Km is 3 point (factor of 1000)
I've seen it - nano-inch. Definitely not an officiam measurement - 1 billionth of an inch (10 to the -9) but coloquially about a 10th of an RCH, give or take a 10th!
I still have at least 2. Somewhere.

The engineering disciplines use either metric or decimal inch. The scientific community has been using metric as standard for many years. Yes, the metric system is a far better system but many resist it because they are used to the imperial system. As an engineer, I really didn't want to see the change either for that reason. At some point though, people are going to have to suffer a little and change over. Not only is it easier to use and to teach, our mechanical products would be much more attractive to foreign buyers. Right now, if one was to buy a piece of American machinery, they have to factor in the cost of tools that may not have any other use. I'm retired, go ahead and switch. :)
