About Imperial cup (imp cup)

The imperial cup is a unit of volume equal to half an imperial pint, approximately 284.1 milliliters. It was historically used in British cooking recipes and is still found in older UK and Commonwealth cookbooks. The imperial cup is distinct from the US legal cup (240 mL) and the Australian metric cup (250 mL). Since the UK's adoption of metric measures, the imperial cup has largely fallen out of use, replaced by milliliters and the 250 mL metric cup.

Older British recipes (pre-1970s) may call for cups measured as imperial cups (~284 mL). A standard UK teacup holds about 1 imperial cup.

About US tablespoon (tbsp)

The US tablespoon (tbsp) is a unit of culinary volume equal to approximately 14.787 milliliters, defined as 3 US teaspoons or half a US fluid ounce. It is a fundamental cooking measurement in the United States for both liquid and dry ingredients. Butter is measured in tablespoons (1 stick = 8 tbsp), as are cooking oils, sauces, and spices. The US tablespoon differs from the Australian tablespoon (20 mL) and the imperial tablespoon (17.76 mL).

One tablespoon of olive oil is about 14 g. A standard butter portion is 1 tbsp (≈ 14 g).
