How to calculate height difference.
Subtract the shorter height from the taller height, using the same unit. For 170 cm and 185 cm, the difference is 15 cm, approximately 5.9 inches.
One inch equals exactly 2.54 cm. One foot equals 12 inches. Values are stored in millimeters, so switching display units preserves the comparison.
What does the ratio show?
The height ratio divides the taller height by the shorter. At 185 cm and 170 cm, the ratio is approximately 1.088. The taller person is about 8.8% taller.
