Thread: Conversion of Plans

Andreg,

Just take the inches and multiply by 25.4 to get your timber size. Gets tricky when they say 1 1/16", but simple math (1 divided by 16 = .062, therefore 1.062 x 25.4 = 26.97 [rounded to 27mm])

Then build it using inches.

I think a 2" x 4" is rough sawn in any case, so dressed would reduce it's size to the 90x45mm referred to.

You dont need a calculator, just use a metris\imperial tape measure and either work exactly to the plan or use the tape to convert metric to imperial or vice versa
as to timber sizes 4 x 2 in the us comes undersize so study the plan carefully and just rework all dimensions to suit

I wonder if you try a Google search for converting metric to imperial what kind of sites you will find. I know they are out there you just have to look and I do not have any bookmarked sorry.

Over here in Canada all measurements are in imperials but all plywood is metric and all you basic routers bits like a straight cutter are imperial. the Metric router bits cost a lot more. Go figure!!!!!!!!

G'Day Team,
Try a program by a bloke called Joshua F. Madison called 'convert'. It's free to copy and distribute but it's too big for me to attach to the BB. You can find it at

http://www.joshmadison.com/software/convert/

or I can email it to you if you want.

It's very good for converting a few numbers, but playing with something like Microsoft Excel may be better if you want to convert long lists of measurements. I had to convert the feet and inches on my house plans to millimetres for the insurance company so I made up an excel table to help me do it. This table is attached and is pretty straightforward.

Hope this helps

What? The insurance company doesn't have a formula to convert square feet or squares into M2? I assume they just need a square metreage to apply a rate to. You would think they'd do a little bit of work for the large amounts of money they are no doubt syphoning out of your pockets.

Andreg, do you actually need to do a "hard" conversion to your plans? (Eg: Hard conversion sheet of ply 8' x 4' = 2440 x 1220, "Soft" conversion = 2400 x 1200) Work out what size timbers you are going to use by soft conversion, making the bench slightly longer/shorter, wider/narrower, taller/shorter shouldn't really matter (as long as it is a good working height for you) The only critical dimensions will be those in your joints and those for your end vice.

I'm a bit thick and have similar problems. Our friends in the USA not only use imperial (???) measurements, they also have a whole different way of interpreting dimensions (board feet for eg).

Try this site - it may throw some light on the subject: http://www.wickes.com/resourceLibrar...lculations.cfm

If ever you understand it - let me in on the secret! And I grew up with yards, roods and rods.
