Complete Listing of almost all Scales:	Z = 1:220	N = 1:160	TT = 1:120	HO = 1:87 (1:87.1)	1/2 = 1:24
Complete Listing of almost all Scales:	OO = 1:76 (1:76.2)	S = 1:64	O = 1:48(1:43.5)	G = 1:32,1:29,1:22.5	1" = 1/12

Convert from Real-life to Scale

Scale Factor	1:	Units

	=
Scale Size

Enter the scaling factor; for 1/32nd scale, enter a 32, for 1/48 scale, enter 48, etc.
In the "Real Size" box, enter the measurement of a real-world object.
Press "inch" or "cm" to select unit of measurement.
Pressing these buttons will recalculate the answer in the selected measurement unit.

Example: You're working in 1/32 scale and you want to represent a pipe that is 8 feet tall in real life. [8 feet is 96 inches (12 x 8)]. Enter 32 in the "scale factor" box and 96 in the "real size" box. Press the "inch" button. Result equals 3 inches. Thus if you cut your piece 3 inches long, that would be equivalent to 8' pipe in the 1/32 scale.

This is the reverse of the calculator above
Enter the scaling factor; for 1/24th scale, enter a 24....
In the "Scale Size" box, enter the measurement of a scaled object.
Press "inch" or "cm" to select unit of measurement.
Pressing these buttons will recalculate output in the selected measurement unit.

Example 1: You have a truck bed that is 6" in length on a model in 1/24th scale. How long is the truck bed in real-life? Enter 24 in the "scale factor" box and 6 in the "scale size" box. Press the "inch" button. Result equals 144 inches or 12 feet.

Example 2: You want to use a piece of 24 gauge wire (.020) as a door handle on a 1/48 scale model. What would the diameter be in real life? Enter 48 in the "scale factor" box and .020 in the "scale size" box. Press the "inch" button. Results .96 or almost one inch in real life size.

Convert from one Model Scale Dimension to another Model Scale Dimension

Example: You have a model part at 1/24th scale and you want to scale that part smaller to set next a different model at 1/32 scale.

	The answer is shown in the UPPER calculator's "Scale Size" box. Thus the part needs to move from: to

Enter the desired scale in the UPPER (Real-life to Scale) calculator's "Scale Factor" box (32 for a 1/32nd scale)
Enter the original model's scale in the LOWER (Scale to Real-life) calculator's "Scale Factor" box(24 for 1/24th scale).
Enter the model's measurement in the LOWER (Scale to Real-life) calculator's "Scale Size" box (i.e. 6 inches).
