cubic centimetre
Học thuậtThân thiện
A scientist carefully measures a liquid using a one cubic centimetre pipette.
Definition
Noun: - A metric unit of volume equal to one thousandth of a liter (0.001 L). It is the volume of a cube whose sides measure exactly one centimetre each.
Usage
The term "cubic centimetre" is used to measure small volumes, particularly in scientific, medical, and engineering contexts. It is a precise unit for quantifying the capacity or size of an object. - It is often abbreviated as cc or cm³. - In many countries, it is the standard unit for engine displacement (e.g., a 1500 cc engine).
Examples
- The syringe holds exactly five cubic centimetres of liquid.
- The diamond has a volume of approximately 0.5 cubic centimetres.
- The car's engine has a displacement of 1600 cubic centimetres.
Advanced Usage
- Scientific Measurement: Used in chemistry to measure reagents and in physics to calculate density (mass per cubic centimetre).
- Medical Dosage: Liquid medicines, especially injectables, are often measured in cubic centimetres (cc), which is equivalent to millilitres (mL).
- Engineering Specification: Used to specify the size of mechanical components or the displacement of internal combustion engines.
Variants and Related Words
- Cubic centimeter: The American English spelling of "cubic centimetre". The definitions and usage are identical.
- Millilitre (mL): A directly equivalent unit of volume (1 cm³ = 1 mL). "Millilitre" is more common in everyday contexts for liquids.
- Litres: A larger metric unit; 1 litre = 1000 cubic centimetres.
Synonyms
- cc (abbreviation)
- cm³ (symbol)
- Millilitre (mL)
Notes
- While "cubic centimetre" and "millilitre" are equivalent in volume, "cubic centimetre" is typically used for solid volumes or engine sizes, whereas "millilitre" is preferred for liquids.
- In automotive contexts, the abbreviation "cc" is almost universally used instead of the full term (e.g., "a 125 cc motorcycle").
