Formula and methodology
Formula: drawing-to-real=length×scale denominator; real-to-drawing=length/scale denominator.
The calculator assumes a ratio of 1:N and leaves the physical unit unchanged. It can be used for maps, plans, models, or diagrams when the scale ratio is already known.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Entered length — minimum 0; maximum 1000000000
- Scale denominator — minimum 1.0E-6; maximum 1000000000
- Conversion direction — 2 choices
Worked example
| Input | Value |
|---|---|
| Entered length | 5 |
| Scale denominator | 100 |
| Conversion direction | drawing-to-real |
5 drawing units at 1:100 represents 500 real units.
Assumptions and limits
- The scale is exactly 1:N and the entered length uses the same unit on both sides.
- The drawing is not distorted differently along its axes.
- Survey calibration, map projection, line thickness, and construction approval are not evaluated.
