I'd flat out freak framing a wall .4064m oc. Hell, I don't even know what the diamonds work out to, 19" & some change.

Most of construction works in feet & inches. Cabinet makers are a bit slow and we function only in inches. I have to think for a second if someone says 13', 5-13/16", whereas I get it pretty quick when its 161-13/16".

How does it work in si? Do you use strictly meters? Or a combination of m and cm? What do you do if you have 62.5cm? Do you call it 5/8 of a meter, or .625 meters?

Yet we haven't had any problem printing EVERYTHING in English and Spanish.

I seem to recall there was a switch over date ,now that you mention it.Not surprising it got nixed.It'll probably happen ( is happening) on it's own accord with the global economy. Just take alot longer.

19", That'll never pass code. laugh

I don't see it too often anymore, (I also don't frame too often anymore), but trusses can be laid out on the diamonds if called for. I don't know the reasoning for such an odd number.

You would simply use 62.5cm. A metric tape measure will have tick marks at 10ths between each base number so 62 plus 5 tick marks. Everything is in 10ths....and 62.5cm is 625mm, 6.25 decimeters (not used that often), and 0.625 meters. It's much simpler than what we do here today. 5/64" is much more difficult to enter in a computer.

To Todd's point, even our framing centers would eventually change to align with the metric system which impacts code and everything else. 16" centers (40.64cm) would become 50cm or 40cm centers or something standard and easily divisible (I wonder what european framing standards are in that regard?).

IMO, the problem everyone has with the metric system is trying to co-relate back to what they are used to. They always think "now how many inches is that?". Instead of just forgetting about the inches and feet.

So we will always measure distance in nm and speed in kts as long the earth turns because it is logic.


The definition of a metre changed over the years as we learnt more about geometry and the planet, but the length stayed the same. A very entertaining question of changing the definition to fit the measurement smile

Ref: http://en.wikipedia.org/wiki/Metre


On the coordinate system used inside GPS units.. It is WGS84 but the output could be anything really. Even UTM or Buckminster Fullers world map.

http://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system
http://en.wikipedia.org/wiki/World_Geodetic_System
http://en.wikipedia.org/wiki/Dymaxion_map

If the logical approach was universally accepted we should have been using knots instead of km/h or m/h in cars as well smile

Being in the science/engineering world, I use metric (SIs) all the time, and have since high school and college (it's not just MIT, BTW).

Being American, I would say that the decimal part of it makes things much simpler, but agree that relating the measurements to the "normal" imperial measurements used in every other part of my life is challenging.

I find that nautical miles are easier to use as a race officer. There are roughly 6000 feet in a nautical mile, so 0.1 nm is 600 feet, which helps when setting a starting line with a GPS.

Dude, come to FL. You are required to toss out your plumb, level and tape measure in order to sit for the GC exam. English or Metric, it doesn't matter... There is no such thing as a straight wall or 90 degree corner in construction here.

16" center ppttthhh... we use "dat oughta doit" measurement.

Only ice I'm interested in is what's floatin' on top of my rum drink.
No worlds for me. I don't feel like I've got the new boat even close to where it should be to spend the jack (Travel,measurements, entry and insurance upgrades) it'll take to do worlds. If work is slow I may try to help out with RC if I can find a place to crash.
