About cups
The measuring cup is the backbone of US home cooking. Standardized by Fannie Farmer in the 1890s to replace vague instructions like 'a tea-cup full,' the US Customary Cup is exactly 8 US fluid ounces. Note that the 'Metric Cup' used in Australia, Canada, and New Zealand is 250 mL, slightly larger than the US cup (approx. 237 mL). Baking with the wrong cup type can lead to recipe failures! cups are commonly used in Baking recipes (flour, sugar), Rice cooker measures, Coffee maker water reservoirs, and Liquid measuring cups.
A standard coffee mug is roughly 1.5 cups.
About teaspoons
The teaspoon (tsp) began as a spoon for stirring tea but became a critical unit of measure for potent ingredients like salt, baking powder, and spices. In the US, it is 1/6th of a fluid ounce (approx. 4.9 mL). The metric teaspoon is exactly 5 mL. This similarity means US and metric teaspoons are often interchangeable for home cooking without issues. teaspoons are commonly used in Spices and seasonings, Baking powder/soda, Vanilla extract, and Medicine (5 mL typically), Sugar in coffee.
A capful of vanilla extract is about 1 teaspoon.
