cm
Input Image distance dᵢ.
cm

Results

-2
m = −dᵢ/dₒ (negative → inverted).

Formula

m = −dᵢ / dₒ.

How to Use

  1. Enter object distance dₒ and image distance dᵢ.
  2. It returns magnification m.

Case Studies

dₒ=30, dᵢ=60 → m=−2

m = −60/30 = −2 (inverted, 2× larger).

FAQ

What does the sign mean?

Negative → inverted real image; positive → upright virtual image.
