About Cubic kilometer (km³)
A cubic kilometer (km³) is the volume of a cube with 1 km sides, equal to one trillion liters (10¹² L). It is used in geoscience, oceanography, glaciology, and climate science to express volumes of ice sheets, ocean basins, volcanic eruptions, and river discharge over long periods. The volume of Earth's oceans is approximately 1,335,000 km³. The Greenland ice sheet contains about 2,850,000 km³ of ice. Major volcanic eruptions are described by the dense rock equivalent (DRE) in km³.
Lake Superior holds about 12,100 km³ of water. A major explosive volcanic eruption might eject 1–1,000 km³ of material.
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).
Cubic kilometer – Frequently Asked Questions
What is a cubic kilometer?
A cubic kilometer (km³) is the volume of a cube 1 km on each side, equal to one trillion liters or one billion cubic meters. It is the standard unit in geoscience for expressing planetary-scale volumes of water, ice, and magma.
How much water is in all of Earth's oceans in km³?
Earth's oceans contain approximately 1,335,000 km³ of water. The world's total freshwater supply is about 35,000 km³, of which most (roughly 26,000 km³) is locked in glaciers and ice caps.
How do scientists measure volcanic eruption volumes in km³?
Volcanologists calculate eruption size as the Dense Rock Equivalent (DRE) in km³ — the volume of solid rock that would result if fragmented material were compressed. The 1815 Tambora eruption ejected roughly 160 km³ DRE, the largest in recorded history.
How many liters are in a cubic kilometer?
One cubic kilometer equals 1,000,000,000,000 liters (one trillion liters or one petaliter). It also equals 10⁹ m³ (one billion cubic meters).
What is the Greenland ice sheet volume in km³?
The Greenland ice sheet contains approximately 2,850,000 km³ of ice. If fully melted, it would raise global sea level by about 7.2 meters. Annual ice loss from Greenland is measured in hundreds of km³ per year.
US tablespoon – Frequently Asked Questions
How many milliliters are in a US tablespoon?
One US tablespoon equals approximately 14.787 mL, typically rounded to 15 mL in culinary contexts. It equals 3 US teaspoons (3 × 4.929 mL = 14.787 mL).
How does the US tablespoon differ from the Australian tablespoon?
The Australian tablespoon is 20 mL — about 35% larger than the US tablespoon (14.79 mL). When using Australian recipes: 1 Australian tbsp ≈ 1.35 US tbsp. This is a significant difference in baking.
How many tablespoons are in a cup?
There are 16 US tablespoons in one US cup (240 mL): 1 cup = 16 tbsp = 48 tsp = 8 fl oz.
How much butter is in a tablespoon?
One US tablespoon of butter weighs approximately 14.2 grams (½ oz). A standard 4-oz US butter stick = 8 tablespoons = ½ cup.
Is a tablespoon the same in US and UK recipes?
No. A US tablespoon is about 14.79 mL; a UK/imperial tablespoon is about 17.76 mL — approximately 20% larger. Most modern UK recipes now use 15 mL metric tablespoons.
