Wings900 - Scale Calculator

Scale					SCALE DOWN (From Real Word to Model) Select the scale to scale down to. In the box marked "input", enter the real world measurement of the object in either in or cm Pressing the "in" or "cm" output button will cause the results to be recalculated and displayed in the unit of measure you've selected. Note: To enter feet & inches, enter them as (feet12)+inches. So 2' 7" would be entered as (212)+7

SCALE UP
(From Model to Real World)

Select the scale you are scaling up from.

In the box marked "input", enter the real world measurement of the object in either in or cm

Pressing the "in" or "cm" output button will cause the results to be recalculated and displayed in the unit of measure you've selected.

Note: To enter feet & inches, enter them as (feet*12)+inches. So 2' 7" would be entered as (2*12)+7

CONVERTING MODEL DIMENSIONS
You can convert measurements from say 1/400 to 1/500. To do this:

Select the model's scale in the LOWER calculator's "Scale" box
Select the output scale in the UPPER calculator's "Scale" box
Put the model's measurement in the LOWER calculator's "Input" box
Click on the "Scale Up/Dwn" button
The result is shown in the UPPER calculator's "Output" box

All this does is scale up the model measurements to 1:1 scale and transfer the result (and unit) to the scale down calculator. It saves you a few keystrokes and button presses, and is probably useful if you're converting a lot of measurements across scales.

*ENTERING FRACTIONS: Expressions entered in the boxes are evaluated before being further processed. Interestingly, if you input a mixed measure like "12-1/2" instead of "12.5", it evaluates the expression as "12 minus 1 divided by 2", the result of which is "11.5". Therefore, you can enter fractional inches if you input the value as "12+1/2" (using "plus" instead of "minus"). The expression will be evaluated as a decimal value. However, if you input the measure as "12 1/2" (without the "plus" or "minus" operator) you will cause a Javascript error because that doesn't evaluate to anything (The "space" character is not a valid mathematical operator).

Because it evaluates the expression you enter, you can enter something like (5*12)+4+(3/4), which is like saying "five feet four and three-quarter inches" (5 feet times 12 inches plus 4 inches plus 3/4 of an inch).
