Density Conversion Formula:
| From: | To: |
Specific gravity to density conversion is a calculation that transforms a dimensionless specific gravity value into density measured in pounds per gallon (lb/gal). This conversion is particularly useful in industries such as petroleum, chemical processing, and fluid mechanics where density measurements are critical.
The calculator uses the conversion formula:
Where:
Explanation: The formula multiplies the specific gravity by the density of water in lb/gal (8.345) to obtain the density of the substance in the same units.
Details: Accurate density calculation from specific gravity is essential for various applications including fluid characterization, quality control in manufacturing, buoyancy calculations, and material selection in engineering projects.
Tips: Enter the specific gravity value (unitless). The value must be greater than 0. The calculator will automatically compute the density in pounds per gallon (lb/gal).
Q1: What is specific gravity?
A: Specific gravity is the ratio of the density of a substance to the density of a reference substance (typically water at 4°C). It is a dimensionless quantity.
Q2: Why use 8.345 as the conversion factor?
A: 8.345 lb/gal is the density of water at standard conditions, which serves as the reference point for specific gravity measurements.
Q3: Can this calculator be used for any substance?
A: Yes, this conversion works for any substance as long as you have an accurate specific gravity measurement relative to water.
Q4: What are typical specific gravity values?
A: Most liquids have specific gravity values between 0.8 and 1.2, though some specialized fluids may fall outside this range.
Q5: How accurate is this conversion?
A: The conversion is mathematically exact. Accuracy depends on the precision of your specific gravity measurement and temperature considerations.
