you get that from drafting too? we had those up all over the place.

thanks for posting it though...its gonna help out alotta people!

Yup. But it didnt have all of them so I had to fill in the blanks.

humm anyone with a calculator (btw windows I one) can calculate this.

I mean, nice effort, but what is the utility of this ?

Its a good reference when converting decimals to fractions. Trust me. I have used these charts more than anyone can imagine for my scratchbuild hot rod.

For instance if you are building 13 inch rotors for a 1/5 scale model the decimal is 2.6" but the fraction is 1-39/64".

Rulers dont have decimals on them so its actually quite useful for converting decimals to fractions.

Um, tack it up on the wall and forget the calculator.

Thanks for the reference, it will definately come in handy.

You obviously don't understand.

I am an engineer and I have a similar chart alongside my PC at work, it's a lot quicker to glance at a chart than to sit and punch buttons everytime you need a conversion.

You've become very crititcal, why is that?

Ill vouch for that. I too do engineering and drafting. I've these charts, and charts very similar to this all over the place. They are very useful. I also see a lot of them at a machine shop I work at over the summer, they have charts with conversions everywhere. It can save a lot of time.

i feel lucky as i was born at a time where the old imperial system was phased out for the metric system. So i never ever learnt the "old" ways.

I find that my degree of accuracy with the mm system to be much more favourable when working on scale models.

1" = 25.4mm

so to get a 13" rotor multiply it by 25.4 then divide by 24 to get the scale for the cars to the nearest 0.1 of a mm! much more accurate than those 37/3 and a 1/5 etc.

plus the japanese use it so again it works out more acurate if you use the same method of measuring as them then you dont get a tolerence creep.

i myself got my first drawing board (a rotoring A4 slide rule) at age 6. and a rotoring A3 age 9. then autocad since 1997 so and have only realy stopped drafting in the past year as a proffession. So i have a good understanding of how to design.

And the metric system is so easy to use.

Funny you mention it Chris, I do all my scale modelling in metric for the reason it's easier and more accurate for me to work with. (aside from the fact I grew up on it, like you, but have learnt both).

Regardless, I think the conversion chart posted here will be useful to some members.

I normally use the metric system because I hate the english system. But for the hot rod I have to use the english system since all the dimensions I find, and squares I have are in the english system.:banghead:
