US teaspoon to Cubic kilometer

One US teaspoon equals approximately 4.929 mL, typically rounded to 5 mL in medicine and 4.93 mL in precise culinary conversions. The metric teaspoon used in Australia and Canada is exactly 5 mL.

A US teaspoon is about 4.93 mL; an imperial (UK) teaspoon is about 5.92 mL — approximately 20% larger. This difference can affect recipes crossing US and UK sources, particularly for spices and leavening agents.

In the US system, 3 teaspoons equal 1 tablespoon (3 × 4.929 mL = 14.787 mL). The metric equivalent is the same ratio: 3 × 5 mL = 15 mL tablespoon.

Not exactly. Medicine dosing uses a standardized 5 mL teaspoon, while the US cooking teaspoon is about 4.93 mL. For medication accuracy, always use a calibrated oral syringe rather than a kitchen teaspoon, which can vary from 3 to 7 mL.

There are 48 US teaspoons in one US cup: 1 cup = 16 tablespoons = 48 teaspoons.

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.

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.

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.

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).

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.
