Density is a kind of property used to measure the properties of the material in sconce, engineering and other requirements.
Density is defined as mass of an object per unit volume.
Measurement of the density is done using verity of units, and we are discussing most of the units used all over the world from the history. From the international systems of units and other inherent systems used are elaborated in this article.
Let’s discuss commonly used units and their characteristics.
Kilogram per Cubic Meter (kg/m³)
The standard unit in the International System of Units (SI), representing mass in kilograms per unit volume in cubic meters. Used by most of the countries all over the world. This would be the most popular unit in the world.
Gram per Cubic Centimeter (g/cm³)
Commonly used in chemistry and material science, g/cm³ expresses mass in grams per unit volume in cubic centimeters.
Pound per Cubic Inch (lb/in³)
Frequently employed in engineering, lb/in³ represents mass in pounds per unit volume in cubic inches. Not common all over the world.
Ounce per Cubic Inch (oz/in³)
Similar to lb/in³ but measured in ounces, oz/in³ finds application in specific engineering contexts. Mostly used to measure the liquid.
Gram per Milliliter (g/mL)
Common in laboratory measurements, g/mL denotes mass in grams per unit volume in milliliters.
Kilogram per Liter (kg/L)
A versatile unit used in various contexts, representing mass in kilograms per unit volume in liters.
Pound per Gallon (lb/gal)
Common in the United States, lb/gal expresses mass in pounds per unit volume in gallons.
Ounce per Gallon (oz/gal)
Similar to lb/gal but measured in ounces, oz/gal is utilized in specific applications in the U.S.
Slug per Cubic Foot (slug/ft³)
A unit used in the Imperial system, slug/ft³ represents mass in slugs per unit volume in cubic feet.
Ton per Cubic Yard (ton/yd³)
Used to measure tons per unit volume in cubic yards and is often used in construction related works.
Megagram per Cubic Meter (Mg/m³)
This is equals to one million grams per cubic meter and used as large unit when specify bulk densities.
Microgram per Cubic Millimeter (µg/mm³)
It is a smaller unit and used to express the mass in micrograms per unit volume in cubic millimeters.
Poundal per Cubic Foot (pdl/ft³)
A unit in the FPS system, represents the mass in poundals per unit volume in cubic feet
Kilogram per Cubic Centimeter (kg/cm³)
This similar type of cement as grams per cubic centimeter but measured in kilograms and is applied in engineering and metallurgy.
Pound per Cubic Foot (lb/ft³)
Frequently used in various industries and it is mass in pounds per unit volume in cubic feet.
Understanding these fifteen units provides a comprehensive overview of the varied ways density can be measured. From the widely recognized kilogram per cubic meter to the more specialized units for unique applications, each unit plays a crucial role in quantifying density in different scientific, industrial, and engineering contexts.
There are other types of units as well but mention above are some the units used to measure the density commonly by various countries. Some other common example is kilonewton per meter cube kN/m³. We use this unit for specify the density of concrete, density of sand, etc. in the engineering works.
