Scale Formula:
From: | To: |
The scale factor represents the ratio between a new value and an old value, showing how much something has been scaled up or down. It's commonly used in mathematics, engineering, architecture, and design to represent proportional relationships.
The calculator uses the scale formula:
Where:
Explanation: A scale factor greater than 1 indicates enlargement, while a scale factor between 0 and 1 indicates reduction.
Details: Scale factors are essential for maintaining proportions in design, creating accurate models, resizing images, and understanding proportional relationships in various fields including mathematics, engineering, and architecture.
Tips: Enter both new and old values as positive numbers. The calculator will automatically compute the scale factor as new divided by old.
Q1: What does a scale factor of 1 mean?
A: A scale factor of 1 means the new value is exactly the same as the old value - there has been no scaling.
Q2: What does a scale factor greater than 1 indicate?
A: A scale factor greater than 1 indicates enlargement or increase in size/quantity.
Q3: What does a scale factor between 0 and 1 indicate?
A: A scale factor between 0 and 1 indicates reduction or decrease in size/quantity.
Q4: Can the scale factor be negative?
A: In standard scaling applications, scale factors are typically positive. Negative values would indicate reflection or inversion, which is not calculated by this simple ratio calculator.
Q5: How is scale factor different from percentage change?
A: Scale factor shows the direct ratio (new/old), while percentage change is calculated as ((new-old)/old)*100. They convey similar information but in different formats.
