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 Cubic meter (m³)
The cubic meter (m³) is the SI derived unit of volume, defined as the volume of a cube with sides of exactly one meter. It is the standard unit for large-volume measurement in science, engineering, construction, and trade. One cubic meter equals 1,000 liters. Natural gas is sold by the cubic meter, concrete is ordered in m³, swimming pools and shipping containers are described in cubic meters, and HVAC airflow is measured in m³/hour.
A standard bathtub holds about 0.15–0.2 m³. A 20-foot shipping container has an internal volume of roughly 33 m³.
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.
Cubic meter – Frequently Asked Questions
How many liters are in a cubic meter?
There are exactly 1,000 liters in one cubic meter. This follows from 1 m³ = 1,000 dm³ and 1 dm³ = 1 liter.
Why is natural gas measured in cubic meters?
Natural gas is billed by volume at standard conditions. The cubic meter is the standard billing unit in most metric countries. In the US, natural gas is sold in cubic feet instead.
How big is one cubic meter?
Imagine a cube one meter on each side — about the size of a large washing machine. It holds 1,000 liters of water, which weighs exactly 1,000 kg (one metric tonne) at standard conditions.
What is a cubic meter used for in construction?
Concrete is ordered and priced by the cubic meter. A typical residential house slab might use 10–20 m³ of concrete. Excavated soil, fill material, and gravel are also sold per cubic meter.
How does m³/h relate to airflow?
Cubic meters per hour (m³/h) measures volumetric airflow rate — common in HVAC, ventilation, and industrial fan specifications. A domestic kitchen extractor fan typically moves 200–600 m³/h. The imperial equivalent is cubic feet per minute (CFM).
