The '''gram per cubic centimetre''' is a unit of [[density]] in the [[CGS system]], and is commonly used in [[chemistry]]. It is defined by dividing the CGS unit of [[mass]], the [[gram]], by the CGS unit of [[volume]], the [[cubic centimetre]]. The official [[SI]] symbols are g/cm<sup>3</sup>, g·cm<sup>−3</sup>, or g&nbsp;cm<sup>−3</sup>. It is equivalent to the units gram per [[millilitre]] (g/mL) and [[kilogram]] per [[litre]] (kg/L). The density of [[water]] is about 1 g/cm<sup>3</sup>, since the gram was originally defined as the mass of one cubic centimetre of water at its [[Properties_of_water#Density_of_water_and_ice|maximum density]] at {{cvt|4|C|F}}.<ref>{{Cite web |title=What Is a Gram in Chemistry? |url=https://www.thoughtco.com/definition-of-gram-604514#:~:text=A%20gram%20is%20a%20unit,which%20water%20has%20maximum%20density). |access-date=2024-11-10 |website=ThoughtCo |language=en}}</ref>
==Conversions==
1&nbsp;g/cm<sup>3</sup> is equivalent to:
: = 1000 g/L (exactly)
: = 1000 [[kilogram per cubic metre|kg/m<sup>3</sup>]] (exactly)
: ≈ {{cvt|1.000000|g/cm3|lb/ft3|disp=out}} (approximately)
: ≈ {{cvt|1.000000|g/cm3|oz/USgal|disp=out}} (approximately)
1 [[kilogram per cubic metre|kg/m<sup>3</sup>]] = 0.001&nbsp;g/cm<sup>3</sup>(exactly)
1 lb/cu ft ≈ {{cvt|1.000000|lb/ft3|g/cm3|disp=out}} (approximately)
1 oz/US gal ≈ {{cvt|1.000000|oz/USgal|g/cm3|disp=out}} (approximately)
