About Cubic centimeter (cm³)
A cubic centimeter (cm³), also written as cc, is the volume of a cube with 1 cm sides, exactly equal to one milliliter (1 cm³ = 1 mL). It is used in medicine for drug dosing, in automotive engineering for engine displacement (a 125 cc scooter engine), and in everyday liquid measurement. The interchangeability of cm³ and mL means a 1 mL syringe and a 1 cc syringe are identical instruments. Engine displacement is expressed in cc for small engines and liters for larger ones (1,000 cc = 1 L).
A standard sugar cube is about 1 cm³. A 1 mL syringe holds exactly 1 cm³. A small motorcycle engine might displace 125 cc.
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.
Cubic centimeter – Frequently Asked Questions
Is a cubic centimeter the same as a milliliter?
Yes, 1 cubic centimeter (cm³) is exactly equal to 1 milliliter (mL). The two units are fully interchangeable. Medical syringes marked in mL and those marked in cc hold identical volumes.
What does cc mean in engine displacement?
In engines, cc stands for cubic centimeters and measures the total swept volume of all cylinders. A 125 cc engine has a piston displacement of 125 cm³ per cycle. Larger car engines are stated in liters: 1,000 cc = 1 L.
How many cubic centimeters are in a liter?
There are exactly 1,000 cubic centimeters in one liter. Since 1 cm³ = 1 mL, this also means 1,000 mL = 1 L — a fundamental metric relationship.
Why is cc used in medicine?
Historically, medical equipment used cubic centimeters before the milliliter became standard SI notation. Both are identical in volume. Most clinical guidelines now prefer mL, but cc persists in some specialties and syringe labeling.
How big is 1 cubic centimeter in everyday terms?
A standard sugar cube, a fingertip, or a 1 mL syringe drawn full all represent roughly 1 cm³. A teaspoon holds approximately 5 cm³. A standard shot glass holds about 44 cm³.
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.
