You can buy a scale from a tool supply store that is marked in 100ths of an inch. Then no conversion to the clumsy fraction system is needed.

I still don't understand why much of this country uses fractions of an inch when they could use decimals. I'm not saying we need to convert to metric, we could just easily convert to decimals like the stock market is finally doing.

If you have a computer program and input the curves into it, you will want decimals anyway.
