    Not sure about that Odie, mine are graduated in ounces. You've got to hit a lot harder if they're in grams! :)

    I forgot about that......many are in ounces, that's right! :eek: (Here, I was trying to be clever!)

    When I observe the weight loss during the seasoning process of roughed bowls, I use grams instead of lb/oz.....It's much easer to mentally conceptualize what's happening when looking at the loss of MC over a time period......any pattern is more noticeable. (It's much easier to work with 1275 grams, than it is 2 lb, 13oz.)

    Odie, did you cut your hairs? Was that done in metric or imperial?

    lol......This more recent photo is closer to the truth, because it shows me as the senior citizen I am! I wish I could look like the other photo forever, but we all know that is pure fantasy! It was about time I tossed that decade+ older photo, and used one that shows me as I look today. Robo asked me about cutting my hair in another thread, because I'm no longer looking like a hippy! Well, I don't really claim the title, but I do feel I'm one that is very uninhibited in the way I look......what you don't see is the ponytail! :D

    Later Sergio.......

    I do some of my own work on my cars and truck. I find it frustrating to have a mixture of SAE and metric on a vehicle. I ran across this with an '86 Buick. Had a dickens of a time with the oil plug until I measured it and found it to be actually 16mm. Ever try to find a 16 mm socket sold as an individual part? Happened to find one in a surplus hardware store. Still have it and don't use it anymore.

    an Aha moment!


    John,

    Many thanks!! Now I know why I'm struggling trying to use these metrical tools on wood grown in the good ol' US of A!

    Certainly gives me a new excuse I never thought of anyway.:D:cool::D

    I am pretty comfortable with both, and even if I wasn't the software I use can do the conversions for me.
    BUT, what cheeses me off (and I hate cheese) is the inaccuracy of the materials we buy/use.
    If I lay out a design with say 1/8" finger joints for cutting with the laser and pop in a pre-bought 1/8" plywood chunk
    does it work? Nope, because it is really a 3mm plywood chunk sold as 1/8". The result is a loose fitting joint and so i have
    to redo the artwork. So it's always best if I have the material in hand so I can measure twice and laser once.

    Nick, I believe it's been a good 15 years since sheet goods were actually manufactured to the thicknesses of their common names. Why are you surprised? Once must of those mills left the US, they've all been metric, even the Canadian's stuff. Just be glad you can calibrate your laser to metric. Us guys with fractional tooling get to keep our bench chisels sharp. :D

    the veneered mdf plywood I get is 1/8". I mean sold as 1/8" and is exactly 1/8".
    It's mostly the layered plywood that is a pain. I really would rather work with hardwoods where they can be planed to spec but the price of hardwoods is killing me!

    Hardwood

    I feel your pain . . .

    Years ago I made it a point to make friends with several local arborists. Two benefits: I'll never run out of oak, hickory, or osage orange firewood, and I have as much domestic hardwood, in any variety that grows within 50 miles of me, as I can want. I have a Woodmizer guy about an hour away, so I harvest, saw to my exact spec, dry and season whatever I want and can use. My shop is stocked with walnut, maple, cherry, sycamore, and poplar, and my turning pile has those + osage, mulberry, dogwood, and whatever the guys happen to be cutting.

    Your local tree-guy can be your BFF. Make him a nice salad bowl and he'll be begging to drop trees off in your driveway:D:D

    Sounds like you've been too laser to measure twice. :rolleyes:

    Canada

    Canada officially went metric in the 70's or 80's , don't remember exactly when. My kids are in early 40's and are not very comfortable in feet and inches, although when working on anything wood related with me have to grin and bear it when I talk inches etc. the wind blows in Km/hr and we drive that way too. I am more comfortable talking about my Sienna van using 10.8 litres per 100 km than getting about 25 or so miles per gallon, so I guess I am converted. I majored in Chemistry and sold analytical balances as my first job, so wasn't a great transition. Had a VW bug in the 60's and a set of metric wrenches, which I still have. Meat and veggies, fruit in the grocery store is sold by the kg. Yet it is advertised in both metric and price per pound being emphasized, for us old folks I guess. Fluids are all metric. Gasoline is in litres and our price bumps are more per litre than they are by the gallon in the US and as good Canadians we take it lying down. Our temps are Celsius and I am more comfortable with C than F. Working in my shop is all done with English measurements except when metric will work better. Oh and if you need an individual socket to complete your set, in either metric or English, find a. Canadian Tire store. Have a rack with both in shallow or deep and guaranteed forever.

    The world would be better off to completely convert to metric, especially since industrialization, and all means of modern connection and communication is making the fabric of humanity so interwoven. Except for mechanics, it would be relatively easy to convert.

    Converting to metric nuts and bolts is coming, but what about thread sizes? Even metric bolt heads still have TPI threads......:confused: Mechanical things will eventually convert, but it's going to take a long time.

    How about language? At present, English is the standard for international communication, but will it be the standard for all time? How will the world convert to an international language? As well, the world would be better off to convert to an international language, but that's a really tough end game to consider.

    How about time? would we be better off with days divided by 100 increments instead of 24 hours? What would "noon" and "midnight" become?:p There will never be a change in the number of days per year, because it's based on a physical reality......just like distance measurements are for metric.

    Celsius instead of Fahrenheit is something that can't be converted soon enough......:D

    Totally agree we would should adopt the metric system as world standard.

    Not gonna happen soon.
    Our country suffers greatly from the not invented here syndrome.
    There is an animosity towards science especially in our congressional leadership.
    As a country we rank pretty low in science education
    Our universities are among the best in the world but most of our PhDs graduates are foreign students.
    change requires a sense of urgency to take place.
    No political benefit for our leaders and no money behind the metric system.

    The army not being held to political nonsense uses metric but calls them NATO standards.

    Unless there is some large widespread economic gain to realized were going to be stuck for a long time.
    The gas companies saw profit in converting pumps to metric. Then saw more profit I converting them to imperial.

    I wish we had gone metric/SI units a long time ago. If we had, we all would be comfortable with it by now and it would be a non-issue and we wouldn't have to have 2 sets of most mechanical tools to work on things. I used metric/SI all through college (science major) and my first job. Then went to work in a lumber yard/building center and had to go back to inches/feet and board feet, etc. A single uniform system would just make things much simpler IMHO.

    Danged stubborn Americans! ;-) Why can't we all just get along?

    Just curious, what's the metric equivalent term for "board/feet"?

    The only reason not to go metric is that SnapOn will loose half of its sales.

    Cubic meters. Here is a web site to help with conversions from cords, board feet, cubic meters....

    **** removed the URL because Bill said it was suspicious *****
    Google "board feet" conversion "cubic meters" and you will get plenty.
