## Definition

A scale factor calculator is a geometry utility that calculates the scaling ratio between two similar figures or scales a given dimension up or down. It calculates the multiplier by dividing the scaled size by the original size, showing the percentage changes and whether it represents an enlargement or reduction. It is commonly used in blueprints, mapping, design modeling, and similarity problems.

## How to Use
