UK teaspoon vs US teaspoon measurements


I have been looking at the following "American" recipe

Moist Vanilla Layer Cake Recipe

and it states:
2 1/2 cups (325g) all purpose flour
2 1/2 tsp baking powder
1/2 tsp salt
3/4 cup (168g) unsalted butter, room temperature
1 1/2 cups (310g) sugar
3 tbsp vegetable oil
1 tbsp vanilla extract
4 large eggs
1 1/4 cups (300ml) milk

1)Are they using US teaspoons? UK Teaspoons = 5ml so not sure how to convert this?
I am sure US teaspoon is Different to UK.
However I just searched on Amazon USA for measuring spoons and it is showing the teaspoon as 5ml?

2)I presume the Cups are the same measurements as UK Cups?

Totally confused, please can you advise.
Thank you.


Hi Sky64

Here is a good chart to follow when converting American Wrights and measures to metric:


The spoon measure is the same. Just be a little more careful with some of the dry measures.

I know from living in Australia, their spoon measures used to be slightly bigger than UK but they’ve been metric for years now. Perhaps that’s what you may have been thinking of.
