Ratio Scaling Calculator
Scale a ratio up or down using a multiplier factor while maintaining exact proportional balance.
- Original ratio: 2 : 5 with multiplier scale factor × 3.
- Multiply Term A: 2 × 3 = 6.
- Multiply Term B: 5 × 3 = 15.
- Verify equality: 6 / 15 = 0.4, which equals original 2 / 5 = 0.4.
- Scaled ratio is 6 : 15.
When to Use Ratio Scaling
Scaling ratios allows you to increase or decrease quantities while preserving exact relative proportions.
🍳 Scaling Recipes:
If a cookie recipe calls for 2 cups flour to 1 cup sugar (2:1) for 12 cookies, multiplying by 2.5 scales the ingredients to 5 cups flour and 2.5 cups sugar for 30 cookies.
📐 Scale Drawings & Maps:
Architectural blueprints and engineering diagrams use scaling factors (e.g. 1:50 or 1:100) to convert real dimensions to model dimensions.
