## Specific Weight to Specific Gravity Calculator

## FAQs

**How do you calculate specific weight from specific gravity?** Specific weight (γ) is calculated by multiplying the specific gravity (SG) of a substance by the density of a reference substance, usually water. The formula is: γ = SG × ρ_ref, where ρ_ref is the density of the reference substance (usually water).

**Is specific weight equal to specific gravity?** No, specific weight and specific gravity are not the same. Specific weight is a measure of the weight of a substance per unit volume, while specific gravity is the ratio of the density of a substance to the density of a reference substance (usually water).

**How do you convert to specific gravity?** To convert a density value to specific gravity, divide the density of the substance by the density of the reference substance. SG = ρ_substance / ρ_ref.

**How do you convert molecular weight to specific gravity?** Molecular weight is not directly convertible to specific gravity, as they are different concepts. Molecular weight is the sum of the atomic weights of the atoms in a molecule, while specific gravity is a ratio of densities.

**How do you find specific weight density and specific gravity?** Specific weight is calculated as weight per unit volume (γ = weight / volume), while specific gravity is the ratio of a substance’s density to the density of a reference substance.

**What is specific gravity times specific weight?** Specific gravity times specific weight doesn’t have a specific physical meaning or formula, as they are different concepts.

**Is specific weight the same as specific density?** Specific weight and specific density both refer to the weight or mass of a substance per unit volume, but they are not the same. Specific weight is the weight per unit volume, while specific density is the mass per unit volume.

**What is the equivalent of specific gravity?** Specific gravity is dimensionless and represents the density ratio of a substance to a reference substance, often water.

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

**How do you convert specific gravity to pounds?** Specific gravity is a dimensionless value, so it cannot be directly converted to pounds. It’s a ratio of densities.

**How do you convert pounds/gallon to specific gravity?** To convert from pounds per gallon to specific gravity, divide the pounds per gallon value by the density of the reference substance in pounds per gallon (usually water).

**What is the relation between specific gravity and density?** Specific gravity is the ratio of a substance’s density to the density of a reference substance. It’s a way to express density in a relative manner.

**How do you calculate specific gravity from weight and volume?** Specific gravity can be calculated by dividing the weight of a substance by the weight of an equal volume of the reference substance.

**How do you convert specific weight to mass?** Specific weight (weight per unit volume) can be converted to mass by multiplying it by the volume.

**Is molecular weight the same as specific gravity?** No, molecular weight is not the same as specific gravity. Molecular weight is the sum of atomic weights in a molecule, while specific gravity is a density ratio.

**What is the relationship between weight and density?** Weight is the force exerted on an object due to gravity, while density is the mass per unit volume of a substance. Weight can be calculated using the formula weight = mass × gravitational acceleration.

**What is the formula of specific weight dimension?** The formula for specific weight is: γ = weight / volume, where weight is in force units (e.g., newtons) and volume is in cubic meters.

**What is the difference between gravity and specific gravity?** Gravity refers to the force of attraction between two masses, while specific gravity is a comparison of the density of a substance to the density of a reference substance.

**How do you convert different units?** To convert between units, you often use conversion factors. For example, 1 kg = 1000 g, 1 m = 100 cm, etc.

**How do you convert kg/m³ to g/cm³?** To convert from kg/m³ to g/cm³, divide the density in kg/m³ by 1000.

**How do you convert kg to g/cm³?** You cannot directly convert kilograms (a unit of mass) to grams per cubic centimeter (a unit of density) without knowing the volume.

**How much force is 1 g in pounds?** 1 gram (g) is approximately 0.00220462 pounds (lb). To convert grams to pounds, divide the weight in grams by 453.59237.

**Is specific gravity the same as weight per gallon?** No, specific gravity and weight per gallon are not the same. Specific gravity is a density ratio, while weight per gallon is a measure of weight.

**What is the relationship between gravity and specific gravity?** Gravity refers to the force of attraction between masses, while specific gravity is a ratio of densities and doesn’t directly involve the force of gravity.
