While I set my oven to 180 and measure out how many grams of flour to use, I pause to see my pool temperature is 28. On my way back I stepped on a bathroom scale that read 80kg and I thought back to secondary school weigh ins where I was in the under 60 bracket.

No, the chart doesn't help. As I said, I don't understand how Imperial shows up so much on them.

Using Imperial for construction is true because we buy/sell to the US. But that's really it, maybe one day we'll weigh things in stone and cook using gas mark.
