Convert wave heights, depths, or measurements from feet to meters. Essential when American or Australian surf reports need translating to metric.

One foot equals exactly 0.3048 meters. In surfing, this conversion is needed constantly. A 4-foot wave is about 1.2 meters — chest to shoulder height.
A 6-foot wave is 1.8 meters — overhead. A 10-foot wave is 3 meters — serious surf that most recreational surfers avoid. When checking forecasts on Surfline (feet) vs Magicseaweed (meters), you need this conversion to compare.
Wave height measurement is already imprecise — forecast models, local measurement conventions, and Hawaiian scale all add variation — but getting the unit conversion right is the baseline.
