Anyone know if there is a site where scale lumber equivalents are posted in English/metric/decimal ?     By the way, is the U.S. the only country using English measurement??  how the he** can you measure 17/64 ths of an inch???

Midwest Scale Lumber (a brand name) lists the different scales and actual measurements on the outside of their packages.  This can be handy.  Most "scale lumber" is most accurate in the 1/4" scale, and for H0 it is in terms of 1/8th" scale instead of the british 1/87.

In 1/8 scale, a 12x12 would be 1/8 x 1/8 or .125 (remember when you made that 283 into a 301?).

Wood trestles are better if built with 9x9's which would be 3/16ths in 0 scale, and 3/32ths for H0

This English System of measurement is based on the human scale where it will relate to people and their actual needs, rather some 'French' ideal based on the diameter of the earth that doesn't relate to anything but the number ten

17/64ths is a BS number.  Smaller than 18/64, and larger than 16/64 which is 8/32 or 4/16 or 2/8 or 1/4", only larger by 1/64.

Don't let all these numbers mix you up.  There is plenty of wiggle room when building in H0.
