Conversion Charts - 03-03-03

Scale to Scale

The following conversion chart is a quick reference for changing scales. To convert from one scale toanother, look up the scale you are at across the top and read down until the row is the scale you want.This is your multiplier. For example, to convert measurements taken from an S scale drawing to N scale,look across the top row for S and down to the N row to get 0.400. Multiply the S dimension by 0.4 to getthe N scale measure.

Read the chart as: FROM [top row] TO [left column]

Inches to Scale Dimensions

The following conversion charts are set up to measure from real world increments to scale increments.Rather than convert 5 scale inches to some number, I chose to use whole numbers that could be measuredwith a ruler or calipers and let the scale inches fall where they might. If you look up 5 scale inches andfind only 4.996 and 5.015, you know that the dimension you set is either a bit over or a bit under and theactual dimension is in between those two settings. I just find it faster to set up to known marks on theruler or caliper. If you need a chart that goes the other way, so you can look up 5 scale inches andget .057405281 (HO scale), it is probably easier to just use a calculator for that kind of conversion (5 divby 87.1 = .0574...).

The tables are set up as Excel spreadsheets (.xls format) or as tab delimited text. The text should set up incolumns in your word processor. I set them up to fit on standard 8.5 x 11 in. paper, used a narrow font,

and set the first tab as a right justified tab followed by a regular left justified tab real close to the first tab.The rest of the tabs should then align the columns correctly. You may have to fiddle with the tabs to getit to look right, switch to a smaller font size, or use a percentage while printing to reduce it a bit. Printingin landscape (horizontal) mode may work well too if you want to use a larger font. If you have aspreadsheet that can read in text files, the setup will be a lot easier to do. Any word processor shouldwork ok.

Some of the files are in multiple formats. These are the ones that I created for myself as the need arose.

Format 1 is to convert proto inches to scale inches, in a two column format. This is the easiest formatto store and read the info from.

Format 2 is the same information in a single column, if you want to format it yourself another way orprint on a dot matrix printer.

Format B is for smaller increments of conversion, to 2.65 scale inches (in N scale.)Format C is in 0.001 increments, with the scale equivalents in inches and feet.
