what unit is density in?

Question

any ideas?

Answer 1

The units of density are unit mass per unit volume.

The SI unit of density is kilograms per cubic meter (kg/m^3).
However, it is very common to see density given in united of g/mL or g/cm^3 as well.
Of course, you can also use non-metric/SI units such as lb/ft^3, but these are much less common in science.

Answer 2

Density=mass/volume=gm/ml

Answer 3

Density is mass per unit volume. The units will vary depending on the type of mass and system in use. Density can also be expressed (incorrectly) as parts per million or equivalent.

Answer 4

Density is in any unit of mass divided by any unit of volume. Volume, in turn, is units of length cubed. The SI unit of density is kg/m^3, but lb/in^3 is commonly encountered in problems with customary units. Other examples of density units are slug/ft^3, g/mm^3, kg/L, or kg/yd^3. Any of these would almost definitely require conversion before you could use them to solve a problem.

Answer 5

Density is a measure of mass per unit of volume. The SI unit of density is the kilogram per cubic meter (kg/m3)

ρ = m/V

where
ρ is the object's density (measured in kilograms per cubic meter)
m is the object's total mass (measured in kilograms)
V is the object's total volume (measured in cubic meters)

Answer 6

Density = mass divide by volume

the unit of mass is gram(g) or kilogram (kg)
the unit of volume is mililiter (ml) = mm^3 or liter (l)=dm^3

so the units of density can be g/ml = g/mm^3 or kg/l= kg/dm^3

Answer 7

The SI unit of density is the kilogram per cubic metre (kg/m3)


ρ is the object's density (measured in kilograms per cubic metre)
m is the object's total mass (measured in kilograms)
V is the object's total volume (measured in cubic metres)

ρ =m/v

Other units:

Mass in terms of the SI base units is expressed in kilograms per cubic meter (kg/m3). Other units fully within the SI include grams per cubic centimetre (g/cm3) and megagrams per cubic metre (Mg/m3). Since both the litre and the tonne or metric ton are also acceptable for use with the SI, a wide variety of units such as kilograms per litre (kg/L) are also used. Imperial units or U.S. customary units, the units of mass include pounds per cubic foot (lb/ft³), pounds per cubic yard (lb/yd³), pounds per cubic inch (lb/in³), ounces per cubic inch (oz/in³), pounds per gallon (for U.S. or imperial gallons) (lb/gal), pounds per U.S. bushel (lb/bu), in some engineering calculations slugs per cubic foot, and other less common units.

The maximum mass of pure water at a pressure of one standard atmosphere is 999.861kg/m3; this occurs at a temperature of about 3.98 °C (277.13 K).

From 1901 to 1964, a litre was defined as exactly the volume of 1 kg of water at maximum mass, and the maximum density of pure water was 1.000 000 kg/L (now 0.999 972 kg/L). However, while that definition of the litre was in effect, just as it is now, the maximum mass of pure water was 0.999 972 kg/dm3. During that period students had to learn the esoteric fact that a cubic centimetre and a millilitre were slightly different volumes, with 1 mL = 1.000 028 cm³. (often stated as 1.000 027 cm³ in earlier literature).



The densest naturally occurring substance on Earth is iridium, at about 22650 kg/m3.
