Here are the steps, you can follow to calculate total magnification of a microscope. To calculate the magnification you need information about the magnification of the objective lens and the eyepiece.

## How to calculate magnification of a compound microscope

- First of all, you need to Look for the magnification marked on the objective lenses (e.g., 4x, 10x, 40x).
- Now check the eyepiece for its magnification. It’s commonly 10x, but it can vary in some cases.

- Multiply the magnification of the objective lens by the magnification of the eyepiece.

[ \text{Total Magnification} = \text{Magnification of Objective Lens} \times \text{Magnification of Eyepiece} ] - If you don’t have information about the eyepiece magnification, assume it’s 1x (no additional magnification), and your total magnification will be equal to the magnification of the objective lens.

## How to calculate magnification of a stereo microscope (Dissecting Microscopes)

Stereo microscopes have two eyepieces and do not use objective lenses with high magnification. The total magnification is calculated differently:

- Check one of the eyepieces for its magnification.

**Stereo microscope Magnification formula**

- The total magnification is twice the magnification of one eyepiece because you are looking through both eyepieces simultaneously.

[ \text{Total Magnification} = 2 \times \text{Magnification of One Eyepiece} ]
