## MODEL SCALES and SCALE CONVERSION CHARTS

 This page contains the following charts: Scale Use Chart Scale Conversion Chart Actual Sizes in Fractional Inches Actual Sizes in Metric Dimensions (mm) Actual Sizes in Standard Drill Sizes Actual Sizes in United States Steel Wire Gage SCALE USE CHART By: Gene Larson Note: The left hand column is the direct ratio for English or metric. For example: 1/48 is 1"=48", or 1'=48', or 1yd=48yd 1mm=48mm, or 1cm=48cm, or 1m=48m, etc The typical math is: 1/48: 1" = 48" = 48/12' = 4' or 1/4" = 1' The formula for converting rope circumference to scale diameter: C/3.1416 x scale multiplier For 1:48: Dia.(scale) = c/3.1416 x (1/48) = c x .00663 .00663 is the scale multiplier factor.

SCALE CONVERSION CHART
By: Buddy McLaughlin

For example: at a scale of 1/4"=1' a fitting 3/4" (0.75) long on the ship will measure 1/64", or .016", or will be a #78 drill on the model.
See red highlight in the chart.
