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 yard (in³)

A cubic yard (yd³) is the volume of a cube with 1-yard sides (3 feet), equal to approximately 764.6 liters or 27 cubic feet. It is the standard unit for ordering concrete, topsoil, mulch, and gravel in the United States. Ready-mix concrete trucks carry 8–11 yd³ per load. A typical house driveway requires 3–5 yd³ of concrete. Landfill capacity and solid waste volume are also measured in cubic yards.

A standard concrete mixer truck carries 8–10 yd³. A garden mulch or topsoil project might require 1–5 yd³.


Cubic kilometer – Frequently Asked Questions

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.

Cubic yard – Frequently Asked Questions

One cubic yard equals exactly 27 cubic feet (since 1 yard = 3 feet, and 3³ = 27). It also equals approximately 764.6 liters.

The US construction industry uses cubic yards for ordering concrete as the traditional imperial bulk material unit. A standard ready-mix truck carries 8–10 cubic yards per load, priced typically at $100–$150/yd³.

Weight varies by material. Concrete weighs roughly 2 tonnes/yd³ (≈ 4,050 lb). Dry soil is about 1.1 tonnes/yd³. Mulch is about 0.4 tonnes/yd³. Gravel is about 1.4 tonnes/yd³.

A typical two-car driveway (20 × 20 ft) at 4-inch thickness requires approximately 5 cubic yards of concrete. At 6-inch thickness, about 7.5 cubic yards.

One cubic yard equals approximately 764.6 liters. Multiply yd³ by 764.6. For example, 5 yd³ = 5 × 764.6 = 3,823 liters.
