Relative Density to Specific Gravity Calculator

FAQs

How do you convert density to specific gravity? Specific gravity is the ratio of the density of a substance to the density of a reference substance, usually water. The formula to convert density (ρ) to specific gravity (SG) is:

SG = ρ_substance / ρ_reference

Is relative density equivalent to specific gravity? Yes, relative density is another term for specific gravity. Both terms refer to the ratio of the density of a substance to the density of a reference substance.

How to calculate specific gravity? To calculate specific gravity, divide the density of the substance by the density of the reference substance. The reference substance is often water at a specified temperature. The formula is:

SG = ρ_substance / ρ_water

How do you find the specific gravity of a gas given the density? If you have the density of a gas and want to find its specific gravity, you need to compare it to the density of a reference substance, typically air or hydrogen. The formula is the same:

SG = ρ_gas / ρ_reference

What is the formula for density and relative density specific gravity respectively?

• Density (ρ): Mass (m) / Volume (V)
• Relative Density / Specific Gravity (SG): ρ_substance / ρ_reference

How do you convert relative density to density? To convert relative density (specific gravity) to density, you need to multiply the relative density by the density of the reference substance. The formula is:

ρ_substance = SG × ρ_reference

How do you find the specific weight from density? Specific weight is the weight of a substance per unit volume. It can be calculated using the formula:

Specific Weight (γ) = ρ × g

Where:

• γ is the specific weight
• ρ is the density
• g is the acceleration due to gravity

Why is relative density called specific gravity? The term “specific gravity” was coined historically because it quantifies how dense a substance is in comparison to the density of water. It’s a specific measure of density relative to water’s density.

What is specific gravity formula units? Specific gravity is a unitless quantity since it’s a ratio of densities. It doesn’t have any specific units.

Is density the same as specific weight? No, density and specific weight are not the same. Density is mass per unit volume, while specific weight is weight per unit volume. The formula for specific weight includes the acceleration due to gravity.

What is the difference between specific gravity and relative density of a gas? There’s no fundamental difference between specific gravity and relative density when dealing with gases. Both terms refer to the same concept: the ratio of the density of a gas to the density of a reference gas, usually air or hydrogen.

What is density with respect to specific gravity? Density refers to the mass of a substance contained in a unit volume. Specific gravity (or relative density) quantifies how much denser a substance is compared to a reference substance, usually water.

What is the basic formula for relative density? The basic formula for relative density (specific gravity) is:

SG = ρ_substance / ρ_reference

What is the formula for relative density of a substance with mass? The formula for relative density of a substance with mass (m) is:

SG = m_substance / m_reference

What is the formula for converting density to mass? The formula for converting density (ρ) to mass (m) is:

m = ρ × V

Where:

• m is the mass
• ρ is the density
• V is the volume

How do you convert weight to volume using specific gravity? To convert weight to volume using specific gravity, you can use the formula:

Volume = Weight / (Specific Gravity × Specific Weight of Reference Substance)

How do you convert kg/m³ to specific gravity? To convert density in kg/m³ to specific gravity, you can use the formula:

Specific Gravity = ρ_substance / ρ_water

What is the difference between specific and relative density? There is no practical difference between specific density and relative density. Both terms refer to the same concept of comparing the density of a substance to a reference substance.

What is the scale for specific gravity? The scale for specific gravity is unitless since it’s a ratio of two densities. It’s typically expressed as a number, and there’s no specific unit associated with it.

What is the normal specific gravity? The normal specific gravity of a substance depends on what reference substance you’re using. For most cases, the reference is water at its densest, which has a specific gravity of 1.0.

Is specific gravity the same as mass? No, specific gravity and mass are not the same. Specific gravity is a ratio of densities, while mass is the amount of matter in an object.

What is the formula for the specific gravity of a gas? The formula for the specific gravity of a gas is the same as for any substance:

Specific Gravity = ρ_gas / ρ_reference

What is the symbol for specific gravity? The symbol for specific gravity is usually written as “SG.”

Does higher specific gravity mean higher density? Yes, a higher specific gravity indicates a higher density of the substance compared to the reference substance.

What do you mean by relative density? Relative density (also called specific gravity) is a measure of how dense a substance is compared to a reference substance, usually water. It’s a dimensionless quantity.

What is the relative density of water? The relative density (specific gravity) of water is 1.0. This is typically used as the reference when discussing specific gravity.

What is the specific gravity of water? The specific gravity of water is 1.0, which is the reference point for specific gravity calculations.

How do you find volume with mass and relative density? To find volume with mass and relative density, you can use the formula:

Volume = Mass / (Relative Density × Density of Reference Substance)

How do you find density without mass? You cannot find density without mass. Density is defined as mass per unit volume, so you need both mass and volume to calculate density.

What is the relationship between center of mass and density? The center of mass is the point where the mass of an object is evenly distributed in all directions. Density, on the other hand, is the measure of mass per unit volume of a substance. While both concepts involve mass, they are not directly related.

Can you use density to convert mass to volume and volume to mass? Yes, you can use density to convert mass to volume and vice versa. The formulas are:

• Volume = Mass / Density
• Mass = Density × Volume

What happens to density if volume is the same and mass increases? If the volume remains the same while the mass increases, the density of the substance will also increase. Density is directly proportional to mass.

How do you convert density kg/m³ to specific gravity? To convert density from kg/m³ to specific gravity, divide the density by the density of the reference substance (usually water):

Specific Gravity = Density (kg/m³) / Density of Water (kg/m³)

How do you convert density to grams and kilograms? Density is typically given in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). If you have density in one unit and want to convert it to the other, use the appropriate conversion factor:

1 g/cm³ = 1000 kg/m³

How is density related to g/cm³? Density is commonly expressed in grams per cubic centimeter (g/cm³), which is a unit that represents mass per unit volume.
