To convert units appearing in Column 1
(left column) into equivalent values in
Column 2 (center column), multiply by
factor in Column 3. Example: To convert
7 gallons into cubic inches, multiply
7 × 231 = 1617. To convert units appear-
ing in Column 2 (center) into equivalent
values of units in Column 1 (left), divide
by factor in Column 3. Example: To con-
vert 25 horsepower into Btu per minute,
divide 25 by 0.02356 = 1061
