WebbIf you know the average slope between two points (see Chapter 4), you can easily calculate the height difference between them. First measure the horizontal distance D in metres between points A and B (see Chapter 2). To calculate the height difference H (in metres), multiply D by the slope S expressed in hundredths: H = D x 0.0S. chrome 4230535Webb3 jan. 2024 · Imagine you’re at the beach, standing on the shoreline (lucky you!).
