Enter the initial length before scaling.
Enter the length after scaling.
Scale Factor:
The scale factor is the ratio of the new length to the original length. It indicates how much the original length has been scaled.

Understanding Scale Factor
The scale factor is a ratio that describes how much a figure is enlarged or reduced in a scaling. It is used in various fields like geometry, cartography, and model making.
Formula:
Scale Factor = (New Length) / (Original Length)
Example:
If you have an original length of 10 cm and you scale it to a new length of 20 cm, the scale factor is 20 / 10 = 2. This means the length has been doubled.
Use Cases:
- Maps: Scale factors are used to represent large areas on smaller maps.
- Architecture: Blueprints use scale factors to represent buildings in a smaller format.
- Model Making: Creating scale models of cars, airplanes, or buildings.
- Image Resizing: Digital images are often resized using scale factors.
