About these units
Cubic Kilometer (km³)
A cubic kilometer represents one billion cubic meters, making it a colossal volume unit used in geology, hydrology, glaciology, and planetary science. Large lakes, ice sheets, magma chambers, and atmospheric water content are often measured in km³. Earth's total ocean volume—about 1.335 billion km³—illustrates the unit's utility in describing planetary-scale systems. The km³ gives scientists a manageable number when dealing with natural features too massive for cubic meters or liters to express conveniently.
Tablespoon (UK) (tbsp (UK))
The UK tablespoon traditionally equals 15 mL, though older definitions ranged from 17.7 to 25 mL depending on period and context. In modern British cooking, the tablespoon is standardized at 15 mL, aligning it with the metric tablespoon used in many countries. This measure remains essential in culinary arts for oils, spices, flavorings, and liquid ingredients, demonstrating how some units survive because of convenience and cultural familiarity, even in highly metricized societies.
