Default Scale 1:20.3

Silly question. If 1/2" = 1 Ft is 1:24 scale, what is 1:20.3 ??

Divide 12 (inches) by the scale:

12 divided by 24 = 0.5 inches. Half an inch equals one foot.

12 divided by 20.3 = 0.5911330049. Call it 0.6
0.6 inches equals a foot.

Standard rulers are divided by 8ths, not 10ths, so you cant find 0.6 neatly on a standard ruler. (Its between 4/8 and 5/8) you can buy rulers divided by tenths of an inch, but you would have to seek one out.

Or, an easier measurent when using a standard ruler: 15mm equals a foot. A centimeter and a half.

Ruler by 10ths commonly available. Same for 12ths.

Search term: "inch = 10ths scale ruler" Internet or Amazon gets you skads of 'em.

Here's an easier method:

If you can imagine it it's on the net. Even if you can't imagine it it's on the net.

Yea, using a scale divided in 10ths of an inch still doesn't put you dead on (round off to .06) so unless
machining parts I don't mess with it. Using 9/16 or 15 mm is plenty close enough for most 1:20.3 building needs and that includes rolling stock, structures, figures, etc.

Yes it does.. a scale divided in 10ths of an inch will give you a mark for exactly 0.6 of an inch. no rounding needed. (you meant .6, but mistakenly said .06)

If you live where there is a store like Michael's, Hobby Lobby, or other art and office supply stores - you know those multi-sided triangular Architect's scales? Get an Engineer's scale for 5 to 8 dollars, such as https://www.michaels.com/westcott-sc.../10102638.html

The New Hampshire Garden Railway Society website has a scale conversion calculator that converts measurements between all of the popular gauge one/G scales and 1:1 units, in feet/inches and metric.
