Microscopy: magnification, image size and real size

You can…

• use: magnification = image size ÷ real size
• rearrange the equation
• convert units correctly (mm ↔ µm)

Common conversions

• 1 mm = 1000 µm
• 1 µm = 0.001 mm

Common mistakes

• mixing units (always convert so both sizes use the same unit)
