3D Object Scaling Calculator
3D Object Scaling: calculate results from explicit inputs, with a formula and worked example.
Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Euclidean geometry. Use one consistent length unit; areas and volumes use its square and cube. Degenerate shapes are rejected. Very thin shapes may lose floating-point precision. Uniform scaling in all directions.
Example Calculation
- Original length: 2 units
- Original area: 6 units²
- Original volume: 4 units³
- Linear scale factor: 3
A scale factor of 3 maps length 2 to 6, area 6 to 54 and volume 4 to 108.
Frequently asked questions
How do I use this calculator?
Enter original length, original area, original volume, linear scale factor. The result updates automatically. Use Reset to restore the example values.
What method does it use?
length′ = k length; area′ = k² area; volume′ = k³ volume. Euclidean geometry. Use one consistent length unit; areas and volumes use its square and cube. Degenerate shapes are rejected. Very thin shapes may lose floating-point precision. Uniform scaling in all directions.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
