Chemical unit conversion tools for bulk chemical pricing and measurements. Use these calculators to convert between the units that actually show up on chemical quotes, freight documents, and certificates of analysis — gallons and liters, pounds and kilograms, price per pound and price per gallon.

Why unit conversions matter when buying chemicals

Bulk chemicals are quoted inconsistently across the industry: one supplier prices a solvent per pound, another per gallon, a third per kilogram delivered. Because every chemical has a different density, you cannot compare those numbers directly — a gallon of acetone weighs about 6.6 pounds while a gallon of water weighs 8.34. Converting every quote to the same unit basis is the only way to compare offers accurately. Our guides show worked examples for acetone, toluene, and isopropyl alcohol.

Common conversions at a glance

One US gallon equals 3.785 liters. One pound equals 0.4536 kilograms. A 55-gallon drum holds about 208 liters; a 275-gallon IBC tote about 1,041 liters. To convert a per-pound price to per-gallon, multiply by the chemical’s weight per gallon (density in g/mL × 8.345). Container-level math — how many drums to a truck, tote fill weights, tanker capacities — is covered in our drum vs. tote vs. bulk guide and chemical drum sizes explained.

Once you have your numbers, get a real delivered price: request pricing and we will quote your chemical all-in, same business day.
