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.
About Cubic hectometer (hm³)
A cubic hectometer (hm³) is the volume of a cube with 100-meter sides, equal to one billion liters (10⁹ L). It is used in large-scale hydrology and reservoir engineering for dam and lake capacities, and is equivalent to one gigaliter (GL). One hm³ of water has a mass of one million tonnes. Reservoirs, aquifers, and annual river discharge volumes are commonly expressed in cubic hectometers, especially in Spanish-speaking countries and international water policy documents.
A large city's annual water supply might require 50–200 hm³. Lake Mead has a capacity of about 36,700 hm³.
Cubic yard – Frequently Asked Questions
How many cubic feet are in a cubic yard?
One cubic yard equals exactly 27 cubic feet (since 1 yard = 3 feet, and 3³ = 27). It also equals approximately 764.6 liters.
Why is concrete measured in cubic yards?
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.
How much does a cubic yard weigh?
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.
How many cubic yards of concrete does a driveway need?
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.
How do I convert cubic yards to liters?
One cubic yard equals approximately 764.6 liters. Multiply yd³ by 764.6. For example, 5 yd³ = 5 × 764.6 = 3,823 liters.
Cubic hectometer – Frequently Asked Questions
What is a cubic hectometer?
A cubic hectometer (hm³) is the volume of a cube 100 meters on each side, equal to one million cubic meters or one billion liters (one gigaliter). It is used in hydrology and large-scale water management.
How many cubic meters are in a cubic hectometer?
One cubic hectometer equals 1,000,000 m³. Since 1 hm = 100 m, 1 hm³ = 100³ m³ = 1,000,000 m³ = one billion liters.
Where is hm³ used in practice?
The cubic hectometer is standard for reservoir capacity in Spanish-speaking countries and international water treaties. Dam capacity tables routinely list volumes in hm³.
Is hm³ the same as a gigaliter?
Yes, 1 hm³ = 1,000,000 m³ = 1,000,000,000 liters = 1 gigaliter (GL). Gigaliter is common in Australian water reporting while hm³ is preferred in European and Latin American hydrology.
How does a cubic hectometer compare to Lake Mead?
Lake Mead, the largest US reservoir, has a capacity of roughly 36,700 hm³. A typical European river dam might hold 50–500 hm³. The scale makes hm³ the natural unit for expressing national water reserves.
