To be fair, the UK went metric many decades ago yet we still use MPH on the roads; and most people would struggle to tell you how tall they are or how much they weigh using only metric measurements.

Haha, yeah. I wanted to turn my flour, milk, and baking powder into pancakes, but it’s surprisingly nightmarish to get the two floating point numbers I need in order to get the ratios right

“Why not simply…”

I assure you that the optimal way to turn flour, milk and baking powder [no eggs? -Ed.] into pancakes is to keep trying different ratios until it works properly.

There's a LOT of variance in flour, milk and baking powder that make attempts at measurement based recipes a fool's errand.

No baking powder would be a start. The rest is just 3-6-3. That is 3 eggs, 6 dl milk, 3 dl flour and a pint of salt and some melted butter or oil.

The road to my hometown is called 363 so easy to remember. Just have to figure out which of them was the milk now again.
