Ounce per Imperial Gallon (oz/imp gal): Understanding Liquid Density

Ounce per Imperial Gallon, abbreviated as oz/imp gal, is a unit of density measurement used to express the mass of a substance (usually a liquid) per unit volume within the Imperial Gallon system. It provides information about the density of a liquid, helping to understand how heavy or light a particular liquid is when measured in this unit.

Definition and Significance

Oz/imp gal represents the mass of one ounce (1 oz) of a substance contained within one Imperial Gallon (imp gal) of liquid. In simpler terms, it answers the question, "How many ounces of a substance are present in one Imperial Gallon of liquid?" This unit is significant because it allows scientists, engineers, and professionals to quantify the density of liquids accurately.

Applications of oz/imp gal

Ounce per Imperial Gallon is used in various industries and applications:

  • Automotive: Automotive engineers use oz/imp gal to measure the density of vehicle fluids like engine oil and coolant.
  • Chemical Industry: Chemists and chemical engineers rely on this unit to assess the concentration of chemicals in solutions.
  • Food and Beverage: It is used to determine the density of beverages, syrups, and other liquid food products.
  • Oil and Gas: In the energy industry, oz/imp gal is used to measure the density of drilling fluids and petroleum products.
  • Laboratory Research: Scientists use it for precise measurements in various laboratory experiments.


Converting oz/imp gal to other density units is essential for different calculations. Here are some common conversions:

  • 1 oz/imp gal = 6.2368 g/L (gram per liter)
  • 1 oz/imp gal = 0.00016036 lb/in³ (pound per cubic inch)
  • 1 oz/imp gal ≈ 0.160358 oz/US gal (ounce per US gallon)
  • 1 oz/imp gal ≈ 0.133526 oz/US gal (ounce per US gallon, fluid ounce)


Ounce per Imperial Gallon (oz/imp gal) is a valuable unit for measuring the density of liquids within the Imperial Gallon system. It aids professionals in accurately assessing the density of various liquids in different industries, contributing to quality control, research, and engineering applications.
