What this conversion means in practice
Road atlases list km; you may need cm on a printed map scale. Multiply kilometers by 100,000.
Two km is 200,000 cm. Useful when a diagram’s scale bar is in cm but the legend lists km.
Map scale 1:50,000 means 1 cm on paper represents 50,000 cm (500 m) on the ground, not 50 km.
How to convert kilometer to centimeter

Example: 2 km × 100,000 = 200,000 cm
