I only have a postal scale so it’s not as accurate as grams but it will have to do.
My original iPad was the iPP 9.7 in an Apple silicone back cover with the ASK.
Second was the iPP 10.5 in a Moko back cover as close to the Apple cover as I could get, with ASK.
Now I have the iPP 11 with the keyboard folio
iPP 9.7, back case, ASK 1 lb. 12.1 oz.
iPP 10.5, back case, ASK 1 lb. 14.3 oz.
IPP 11, keyboard folio 1 lb. 12.2 oz
