| barrel of oil equivalent | A unit of energy equal to the amount of energy contained in a barrel of crude oil. Approximately 5.78 million Btu or 1,700 kWh. A barrel is a liquid measure equal to 42 gallons. (05 Dec 1998) |
| gold equivalent | A unit of power of the protective colloids; the number of milligrams of protective colloid just sufficient to prevent the precipitation of 10 ml of a 0.0053 to 0.0058% gold solution by the action of 1 ml of a 10% sodium chloride solution. Synonym: gold number. (05 Mar 2000) |
| gram equivalent | The weight in grams of an element that combines with or replaces 1 gram of hydrogen, the atomic or molecular weight in grams of an atom or group of atoms involved in a chemical reaction divided by the number of electrons donated, taken up, or shared by the atom or group of atoms in the course of that reaction, the weight of a substance contained in 1 liter of 1 normal solution; a variant of. Synonym: combining weight, equivalent weight. (05 Mar 2000) |
| metabolic equivalent | The oxygen cost of energy expenditure measured at supine rest (1 MET = 3.5 ml O2 per kg of body weight per minute); multiples of MET are used to estimate the oxygen cost of activity, e.g., 3 to 5 METs for light work; more than 9 METs for heavy work. (05 Mar 2000) |
| roentgen-equivalent | <radiobiology> A unit of dose equivalent to that quantity of ionizing radiation of any type that produces in man the same biologic effect as one rad of X-rays or gamma rays; the number of rems is equal to the absorbed dose, measured in rads, multiplied by the quality factor of the radiation in question.100 rem = 1 Sv. (05 Mar 2000) |
| roentgen-equivalent physical | <radiobiology, unit> A roentgen equivalent physical is a unit of absorbed radiation approximately equivalent to a roentgen, an international unit of x- or gamma-radiation. An obsolete unit of measurement; that quantity of ionizing radiation of any kind which, upon absorption by living tissue, produces an energy gain per gram of tissue equivalent to that produced by 1 roentgen of X-rays or gamma-rays. Acronym: rep See: rad. (05 Mar 2000) |
