Haw. Code R. § 4-186-4
As used in this chapter: "Actual density" or "relative density" means the observed density or observed relative density, respectively, determined at a product temperature of sixty degrees Fahrenheit or which has been corrected to sixty degrees Fahrenheit, and is expressed by the relationship: relative density sixty/sixty degrees Fahrenheit equal one hundred and forty-one and five tenths divided by the quantity API gravity at sixty degrees minus one hundred and thirty-one and five tenths (Relative density 60/60°F = 1415);
"Administrator" means the administering officer of the quality assurance division or any qualified person so designated by the chairperson of the board of agriculture;
"After-market additive" means a commodity marketed for addition, by the consumer or a person other than Require the manufacturer, to a liquid petroleum product for purposes of enhancing the characteristics of the liquid petroleum product or its performance, as in an internal combustion engine;
"API" means American Petroleum Institute;
"API gravity" means the relationship expressed by degrees API equal one hundred and forty-one and five tenths divided by relative density as sixty/sixty degrees Fahrenheit, minus one hundred thirty-one and five tenths, and is abbreviated °API. ("API = Relative Density 60/60°F - 131.5);
"ASTM" means American Society for Testing and Materials International;
"Base-gasoline" means the gasoline component of a gasoline-ethanol blend;
"Degrees API" means API gravity, which is a special density scale adopted in 1921 by the national bureau of standards in lieu of the Baume scale;
"Density" means the mass per unit volume;
"Ethanol" means nominally anhydrous ethyl alcohol meeting ASTM D4806. Ethanol is intended to be used as a gasoline blend component for use as a fuel in a spark-ignition internal combustion engine. The denatured fuel ethanol is first made unfit for drinking by the addition of a substance approved by the Alcohol and Tobacco Tax and Trade Bureau (ATTB) prior to blending with gasoline;
"Gasoline" means a volatile mixture of liquid hydrocarbons, generally containing small amounts of additives, suitable for use as a fuel in spark-ignition, internal combustion engines, and which may contain ethanol;
"Gravity" means API gravity;
"Inspector: means an employee of official of the department of agriculture authorized to administer and enforce this chapter;
"LPG" means liquefied petroleum gas in the liquid state;
"Market" or "marketing" means the activities and actions leading to the sale or potential sale of a commodity. It includes all aspects of trade and commerce, labeling, merchandising, mercantiling, and selling the net measure of a commodity;
"Observed density" or "observed relative density" means the value observed on the scale of a hydrometer when the scale indication is read at the point where the principal surface of the liquid would intercept the stem of the immersed hydrometer if there were no meniscus, the principal surface being read as a flat plane rather than an ellipse. It is an incorrect indication of the density of the product unless the liquid temperature is, or is corrected to, sixty degrees Fahrenheit. (See "actual density");
"Petroleum Measurement Tables" means the following tables, ASTM D1250-08(2013)el, Standard Guide for Petroleum Measurement Tables as published by the ASTM October 2015:

"Petroleum product" means automotive gasoline, diesel fuels, fuel oils, liquefied petroleum gas both liquid and vapor, residuals, distillates and fractions, kerosene, aviation fuels, turbine fuels, solvent, hydrocarbons or synthetics, crude oil, lubricating oil, or any other oil or distillate or blends of the above, or any other product that may normally be considered a petroleum product, and synthetic natural gas or natural gas and manufactured gas or blends thereof;
"Relative Density 60/60°F" means the ratio of the weight of a given volume of oil at sixty degrees Fahrenheit to the weight of the same volume of water at sixty degrees Fahrenheit, both weights being corrected for the buoyancy of air;
"SAE" means the Society of Automotive Engineers International, or SAE International;
"Sealed" or "in seal" means a measurement standard, licensed for current use, which has been approved as to type by the administrator, and tested by the administrator, inspector, or a registered service person for correctness and found to be in compliance and to which has been affixed a seal attesting to such correctness and compliance. A device, which has been relocated or exchanged subsequent to sealing and which by design is not considered portable shall, when any such action is undertaken, lose its seal;
"Sixty/sixty °F" is a dimensionless number, expressing the ratio of the weight of a specific volume of petroleum product, the temperature of which is sixty degrees Fahrenheit, to the exact same volume of water, the temperature of which is sixty degrees Fahrenheit. It is abbreviated 60/60°F; and
"Viscosity" is a measure of the resistance of a fluid to flow.
