The enzyme unit, or international unit for enzyme (symbol U, sometimes also IU) is a unit of enzyme's catalytic activity. [ 1 ] 1 U (μmol/min) is defined as the amount of the enzyme that catalyzes the conversion of one micro mole of substrate per minute under the specified conditions of the assay method .
1 IU of rhEGF is defined as the potency of 0.001 μg of a rhEGF in the "91/530" standard vial. One manufacturer reports that its rhEGF is 1.4 times as potent as the 91/530 standard. [7] 12.5 IU of oxytocin is defined as the potency of 21 μg of pure peptide in the "76/575" standard vial. [8]
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
The output of {{convert}} can display multiple converted units, if further unit-codes are specified after the second unnamed parameter (without the pipe separator). Typical combination output units are listed below in column 7. {{convert|55|nmi|km mi}} → 55 nautical miles (102 km; 63 mi) {{convert|1|oz|ozt g gr}} → 1 ounce (0.91 ozt; 28 g ...
In chemistry, the mass concentration ρ i (or γ i) is defined as the mass of a constituent m i divided by the volume of the mixture V. [1]= For a pure chemical the mass concentration equals its density (mass divided by volume); thus the mass concentration of a component in a mixture can be called the density of a component in a mixture.
In 2020, Donald Trump pardoned cybersecurity executive Chris Wade for crimes that had been sealed. Unsealed documents show he was part of a sophisticated spam email operation busted by an informant.
The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
While shelters have seen a higher rate of dogs being returned to owners, adopted, or living in the shelter system, cats faced euthanasia 10 times more often than dogs in the first half of 2024.
