The most direct definition of magnification: how tall the image is compared to the thing itself. A microscope objective marked 40× makes a 5 μm cell appear 200 μm across to the next stage of the instrument. Combined with m = −d_i/d_o, the two magnification formulas let you convert freely between distances and sizes in any lens problem.
