About Imperial tablespoon (imp tbsp)
The imperial tablespoon is a unit of volume equal to approximately 17.758 milliliters, defined as five-eighths of an imperial fluid ounce. It is used in older UK and Commonwealth cooking recipes. The imperial tablespoon is larger than the US tablespoon (14.787 mL) but smaller than the Australian tablespoon (20 mL). Modern British and Commonwealth recipes have replaced it with the 15 mL metric tablespoon, but it persists in pre-metrication cookbooks.
Older British recipe books specify tablespoons of approximately 17.8 mL — larger than a US tablespoon but smaller than an Australian one.
About Cubic mile (in³)
A cubic mile (mi³) is the volume of a cube with 1-mile sides, equal to approximately 4.168 trillion liters or about 4.168 km³. It is used in geoscience, hydrology, and environmental science to describe volumes of large water bodies, atmospheric water vapor, volcanic eruptions, and glacial ice. The total volume of Earth's oceans is approximately 320 million cubic miles. The unit is primarily used in US scientific and journalistic contexts.
The Great Lakes together contain about 5,440 mi³ of fresh water. The Amazon River discharges roughly 1.5 mi³ per day.
Imperial tablespoon – Frequently Asked Questions
How many milliliters is an imperial tablespoon?
One imperial tablespoon equals approximately 17.758 mL — larger than the US tablespoon (14.79 mL) and smaller than the Australian tablespoon (20 mL). Modern UK metric tablespoons are standardized at 15 mL.
What is the most common baking disaster caused by tablespoon size confusion?
Leavening failure. Baking powder and baking soda are measured in tablespoons, and the difference between a US tablespoon (14.8 mL), an imperial tablespoon (17.8 mL), and an Australian tablespoon (20 mL) is 15–35%. Too much baking soda makes bread taste metallic and soapy; too little and it does not rise. A British grandmother's scone recipe used in an American kitchen with US tablespoons will under-leaven by 20%. Professional bakers avoid this entirely by weighing leavening agents in grams.
Is the imperial tablespoon still used in UK cooking?
No. Modern UK cooking uses 15 mL metric tablespoons. The imperial tablespoon (17.76 mL) appears only in pre-1970s British cookbooks.
How many imperial teaspoons are in an imperial tablespoon?
One imperial tablespoon equals 3 imperial teaspoons (each ≈ 5.92 mL), giving 3 × 5.92 = 17.76 mL. The same 3:1 ratio as in US and metric systems, though the absolute sizes differ.
What is the standard tablespoon size in Australia?
The Australian tablespoon is 20 mL — the largest of the major English-language cooking tablespoons. Australian recipes therefore use fewer tablespoon counts than US or UK recipes for the same volume.
Cubic mile – Frequently Asked Questions
How many liters are in a cubic mile?
One cubic mile equals approximately 4.168 × 10¹² liters (about 4.17 trillion liters) or roughly 4.168 km³. It is used only for planetary or geological scale volumes.
How much water is in the oceans in cubic miles?
Earth's oceans contain approximately 321 million cubic miles (1.335 billion km³) of water. The Pacific Ocean alone accounts for about 170 million cubic miles.
How does a cubic mile compare to a cubic kilometer?
One cubic mile equals approximately 4.168 cubic kilometers (km³). Geoscientists generally use km³; cubic miles appear mainly in US-origin journalism and older literature.
Is the cubic mile used in science?
The cubic mile is used in US-origin geoscience and hydrology texts for Great Lakes volumes, glacier mass loss, and ocean capacity. International scientific literature generally uses km³ instead.
How many cubic miles of water are in the Great Lakes?
The five Great Lakes together contain approximately 5,440 cubic miles (22,671 km³) of fresh water — about 21% of the world's surface fresh water. Lake Superior alone holds about 2,900 mi³.
