Real distance
2.5 km
Scale1 : 50,000

Calculation steps

  1. 1Map distance 5 cm = 50 mm
  2. 2Scale 1:50,000 → real distance = map distance × 50,000
  3. 350 mm × 50,000 = 2,500,000 mm
  4. 4Convert unit: 2,500,000 mm = 2.5 km

A larger denominator means a SMALLER scale: 1:1,000 is a larger (more detailed) scale than 1:1,000,000. Area scales with the square of length — on a 1:500 plan, 1 cm² represents 250 m² in reality.
