Conversion Factors to Calculate Pounds
GASES – To convert from standard cubic feet (SCF) to pounds, multiply by:
Hazardous Material
Acetylene
Ammonia
Argon
Bromine
Carbon Dioxide
Chlorine
Fluorine
Helium
Example:
lbs/scf
0.073
0.048
0.112
0.446
0.1235
0.201
0.102
0.0111
Hazardous Material
Hydrogen
Methane
Neon
Nitrogen
Nitrous Oxide
Oxygen
Propane
lbs/scf
0.0056
0.0448
0.544
0.078
0.123
0.0834
0.123
250 SCF of Oxygen x 0.0834 = 20.85 pounds
Amount of gas multiplied by the conversion factor
LIQUIDS – To convert from gallons to pounds, multiply by:
Hazardous Material
Ammonium Hydroxide (Aqueous)
Antifreeze (New or Waste)
DF2000 (dry cleaners)
Diesel
Ethanol
Formaldehyde
Gasoline
Hydrochloric Acid (muriatic)
Isopropyl Alcohol
Kerosene
MEK
Motor Oil (New or Used)
Paint
Perchloroethylene
Propane
Sodium Hydroxide
Sodium Hypochlorite (liquid chlorine)
Sulfuric Acid
Water
lbs/gal
7.75
8.8
6.4
7.3
6.5
8.7
6.0 (range 5.8-6.2)
9.67
6.55
7.0
7.0
7.5 (range 7.3-7.8)
8.0
13.4
4.5
12.8
10.2
15.3
8.3
Example: 55 gallons of used oil x 7.5 = 412.5 pounds
For determining pounds of liquid hazardous materials not listed above, get specific gravity number
from the Material Safety Data Sheet (MSDS). Multiply specific gravity number times 8.3. Then
multiply that number times the maximum amount of gallons facility stores. This is the number of
pounds that facility stores.
Example:
ChemKool MSDS lists specific gravity as 1.08
1.08 x 8.3 lbs/gal = 8.964 lbs/gal
55 gallons of ChemKool x 8.964 = 493.02 pounds
