Bar (unit) mb (rather than the proper mbar) to denote the millibar. Between 1793 and 1795, the word bar was used for a unit of weight in an early version of the metric system. Atmospheric air pressure is often given in millibars, where standard atmospheric pressure at sea level is defined as 1013.25 mbar, 101.325 kPa, 1.01325 bar, which is about . Despite the millibar not being an SI unit, meteorologists and weather reporters worldwide have long measured air pressure in millibars as the values are convenient. After the advent of SI units, some meteorologists began using hectopascals (symbol hPa) which are
Commission for Regulation of Utilities is proposed that the wastewater service be charged per unit product consumed. Commission for Regulation of Utilities The Commission for Regulation of Utilities (CRU), formerly known as the Commission for Energy Regulation (CER, ) is Republic of Ireland's energy and water economic utility regulator.

On the transmission network, generally the high voltage lines deliver electricity from Ireland's generation sources to the transformer stations, where the electricity voltage is reduced and taken onwards through the distribution system to individual customers' premises. There are also about 18 very large commercial customers directly connected to the
