Conversion Charts
Here are some handy conversion tables. We need to use either Imperial or Metric, and not mix them in baking, as the conversions aren’t exact

NB: A pint isn’t always a pint: in British, Australian and often Canadian recipes you’ll see an imperial pint listed as 20 fluid ounces. American and some Canadian recipes use the the American pint measurement, which is 16 fluid ounces. |
If you want to calculate a different amount, try the site Aqua Calc, it seems to have most things.
