Calculating wing loading?

Can anyone remember the formulae for calculating wing loading please? , Mel.

Just googled it and this came up Mel

How to Calculate Wing Loading

In this example, we will use an aircraft weighing 5-1/2 lbs (5 lbs 8 oz.) with 600 square inches of wing area. Calculating the wing loading requires that the wing area be converted to square feet (ft2) and pounds to ounces.

1) Convert the area to square feet. There are 144 (12 x 12) square inches in a square foot.

600 in2 ÷ 144 = 4.17 ft2

2) Convert the total empty weight (ready-to-fly with no fuel) to ounces. There are 16 ounces in a pound.

5.5 lbs x 16 = 88 oz.

3) Divide the weight by the area:

88 oz. ÷ 4.17 ft2 = 21.1 oz./ft2

Using round numbers, this gives the aircraft a wing-loading of 21 oz./ft2 or

You can perform the entire calculation in one shot using simple substitution:

(Weight x 2304) ÷ Wing Area

Where weight is in pounds and wing area is in square inches

Plugging the numbers from this example into the above formula gives us this:

( 5.5 x 2304 ) ÷ 600 = 21.1 oz./ft2

For multi-wing aircraft, divide the overall weight of the aircraft by the total wing area for all wings.

Thanks for that Bri, works a treat.
