You're not supposed to mix imperial and metric units of measurements up.
Certainly not when baking or preserving. Or doing any kind of engineering calculations. Unit consistency and all that LOL... I still have my conversion tables somewhere.


Have you thought of cutting a mountain bike inner tube(on the inside) and using that?
I'd need a fair few inner tubes to glue and layer. Which I don't have.
