Wing-loading is a number indicating the load per unit of surface of a parachute.
The USA being the biggest market and using the imperial system it’s most of the time expressed in Pounds per square feet (lbs/ft² or lbs/sqft).
You can calculate yours easily by dividing your exit weight (your weight with all your equipment) in pounds by the size of your canopy in square feet.
WL = Weight (lbs) / Size (sqft)
The size of parachutes is usually expressed in square feet but if you only know your exit weight in kilograms it’s not much more complicated, you just need to convert it to pounds using a 2.2 factor.
