Can density be measured with SI units?
Density, however, can be measured in a wide variety of units, like g/cm^3 or g/ml. The SI unit for density is kg/m^3 or kilograms per meters cubed. Density, however, can be measured in a wide variety of units, like g/cm^3 or g/ml. What is the standard unit of density?
What is the fundamental SI unit?

- Length - meter (m)
- Time - second (s)
- Amount of substance - mole (mole)
- Electric current - ampere (A)
- Temperature - kelvin (K)

What is density in science?
The term ‘Density’ refers to the measure of the mass of an object or body having unit volume. It is denoted by the symbol ρ or can be simply represented by the letter D. Quantitatively, density is mass divided by volume. The density of a given material shows its denseness in a specific area. It is usually a measure of how tightly the particles ...
How to find density of an object?
Greek scientist Archimedes discovered the principle of density. The density of an object shows how heavy it is at a constant volume. Mathematically, the density of an object can be calculated with the help of the formula specified below: Density = Mass/Volume or ρ = m/v, where ρ = Density, m = mass, and v = volume.
Why are solids denser than gases?
Solids are typically denser than liquids and gases as the particles are tightly packed with very little space among them. In liquids, particles are not very tightly packed, due to which, they are less dense than solids but denser than gases, which have free-flowing particles.
What is absolute density?
Absolute density refers to the mass of any substance per unit volume of a material. It is usually expressed in g/cm3.
What are the two types of density?
Types of Density. Usually, the density is of 2 types, one is absolute density, and the other is relative density. Relative density is also known as specific gravity, which is the ratio of the density of a material to the density of reference material. Usually, the reference material is water. Specific gravity is a relative quantity with no units.
What is the specific gravity of gold?
For example, the density of gold is 19.32 g/cm³, and so the specific gravity is 19.32.
What is the SI Unit?
SI unit is an international system of measurements that are used universally in technical and scientific research to avoid the confusion with the units. Having a standard unit system is important because it helps the entire world to understand the measurements in one set of unit system. Following is the table with base SI units:
What are the SI base units?
SI Base Units. These are the fundamental units and are considered as the building blocks of the system. All the other units are derived from the SI Base units. One of the examples is that the SI unit of mass is kilogram. This is often confused with grams.
What is the unit of luminous intensity?
Unit of luminous intensity, candela (cd): Candela is the SI unit of luminous intensity and is defined by the fixed value of the luminous efficacy. It should be noted that these 7 units are assumed to be mutually independent and hence are called base units.
How many physical quantities are there?
There are seven fundamental physical quantities they are: length, mass, time, electric current, temperature, amount of substance and light intensity.
What is the unit of thermodynamic temperature?
Unit of thermodynamic temperature, Kelvin (K): Kelvin is the SI unit of thermodynamic temperature and is defined by taking the fixed value of Boltzmann constant k = 1.380649×10 -23.
What is the SI system?
SI system is based on the precise and definite standards. The base used in SI system is 10, which makes the conversion easier. Latin and Greek prefixes are used in SI system and these refer to the numbers. Without the use of conversion factors, the SI units can be derived from one another.
What is the unit of time for second?
Unit of time, second (s): Second is the SI unit of time and is defined by taking the fixed value of Cesium frequency. It is expressed as s 1.
Unit of Density
- Though SI unit of density is kg/m³, for convenience we use g/cm³ for solids, g/ml for liquids, and g/L for gases.
- Density can be explained as the relationship between the mass of the substance and the volume it takes up.
- Though SI unit of density is kg/m³, for convenience we use g/cm³ for solids, g/ml for liquids, and g/L for gases.
- Density can be explained as the relationship between the mass of the substance and the volume it takes up.
- In a qualitative term, it shows how much heavy an object is at constant volume.
- Different substances have different density, which means for the same volume of different substances weigh differently.
Si Unit of Density
- Each substance has a specific density. Generally, the density of water (which is approximately about 1 gram/cubic centimeter) is taken as the standard value for calculating the density of substances. However, the SI unit of Density is measured using kilograms per cubic meter (kg/m3).
Applications of Density in Real Life
- Many applications of density are there in our real-life like a few examples are in pipe design, shipbuilding, helium balloons, weight distribution in the airplane, and the fact that ice floats on water. 1. The knowledge of the densities of two substances helps you in separation techniques. For example, separation of oil from water. Leakage of an oil tank in the ocean then o…
Solved Examples
- Question 1:
Take two boxes that have the same volume. Fill the first box with x balls and the second box with 6x balls. If the mass of each ball is the same, which box would weigh more? Solution: The box that has more balls has more mass per unit of volume. Here the first box contains x number of balls … - Question 2:
Calculate the density of water if it has a mass of 1160 Kg and a volume of 1 m3? Solution: Given, Mass = 1160 Kg Volume = 1 m3 Density is given by the formula: Density = Mass/Volume ρ = 1160/1 = 1160 kg/m3
