About US liquid gallon (gal)
The US liquid gallon is a unit of volume equal to 4 quarts, 8 pints, or 128 US fluid ounces, approximately 3.785 liters. It is the primary large liquid volume unit in the United States, used for fuel pricing at the pump, milk and juice packaging, and paint. US fuel economy is measured in miles per gallon (MPG). The US gallon is about 17% smaller than the UK imperial gallon (4.546 L), causing significant differences in fuel economy comparisons.
A gallon jug of milk is 3.785 L. Petrol (gasoline) is priced per US gallon at every US fuel station.
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.
US liquid gallon – Frequently Asked Questions
Why does the US still price fuel per gallon when the rest of the world uses liters?
US fuel infrastructure — pumps, tax law, pipeline contracts, and consumer expectations — is built around the gallon. Federal and state fuel taxes are levied per gallon; EPA fuel economy standards use miles per gallon; and consumers benchmark prices against a gallon reference ("$3 a gallon"). Switching to liters would require reprogramming every pump, rewriting tax code, and re-educating 330 million people who compare prices by the gallon. Canada made the switch in the 1970s during a broader metrication push, but the US never had the political will for a comprehensive changeover.
Why is the US gallon smaller than the UK gallon?
The US gallon (3.785 L) is based on the Queen Anne wine gallon of 1707 (231 cubic inches). The UK imperial gallon (4.546 L) was defined in 1824 as the volume of 10 pounds of water. The two systems diverged after US independence.
How does US MPG compare to L/100km?
To convert: L/100km = 235.2 ÷ MPG (US). A car achieving 30 MPG uses about 7.8 L/100km. UK MPG values are always higher than US MPG for the same car because the imperial gallon is larger.
How many gallons of water does a person drink per day?
Recommended daily water intake is about 2–3 liters (roughly 0.5–0.8 US gallons). The commonly cited "8 glasses a day" ≈ 64 fl oz ≈ 0.5 gallons ≈ 1.9 liters.
How many gallons does a car fuel tank hold?
Most US passenger cars have fuel tanks of 10–20 gallons (38–76 liters). Compact cars are typically 10–13 gallons; mid-size cars 14–17 gallons; SUVs and trucks 18–36 gallons.
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.
