How it works
Use real image magnification with the units stated beside the fields. This form solves for magnification magnitude; enter the known quantities in Real image distance, Real object distance.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Real image distance | 0.44999999999999996 m | Formula symbol: vᵢ. Required unit: m. Must be greater than zero. |
| Real object distance | 0.30000000000000004 m | Formula symbol: u. Required unit: m. Must be greater than zero. |

Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
When can I use the magnification magnitude result?
This model uses positive magnitudes. This is magnification magnitude for a real image. Signed magnification is negative on this branch, indicating inversion; this form reports size, not orientation.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
