title: convert pounds to gallons with a known specific gravity
body: <p>I'm working at a terminal that does liquid storage.  I need to write a calculator that can result in a pound and gallons.</p>
  
  <p>For trucks, they come in on a scale to get weighed when its full, empty the liquid, then get back on the scale empty.  This scale measures in pounds.  The NET is the amount of liquid from the truck.</p>
  
  <p>Two questions:</p>
  
  <p>Q1) -------</p>
  
  <p>If the liquid is 2-Ethylhexanol, how do I convert it to gallons knowing:</p>
  
  <p>a) 45000 pounds of product (net)
  b) Specific Gravity is 0.833 (20 °C)
  c) weight of water 8.3378 per gallon</p>
  
  <p>is the calculation 8.3378*.833 = 6.9453817 pounds per gallon? Is so, then do I just simply multiply 45000*6.9453817 to get the gallons?</p>
  
  <p>Q2) --------</p>
  
  <p>After I figure out the gallons.  Then I need to figure out how to do Volume Correction Factors.  For example, at 72 degrees Fahrenheit, how many gallons of volume does it take up? At 60 degrees using the example above it takes up 6.945 gallons.  I should multiple the 6.945*VCF.  What is the formula for getting the VCF?</p>
