In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . [1] In the field it is measured using a mud scale or mud balance. Mud can weigh up to 22 or 23 ppg. A gallon of water typically weighs 8.33 pounds (or 7.48 ppg).
1.51% (1 in 66) – (1 foot (0.3 m) per 1 chain (20 m)) New South Wales Government Railways, Australia, part of Main South line. 1.25% (1 in 80) – Wellington Bank, Somerset , UK 1.25% (1 in 80) – Rudgwick , UK ( West Sussex ) platform before regrading – too steep if a train is not provided with continuous brakes .
To convert heat values to joules per mole values, multiply by 44.095 g/mol. To convert densities to moles per liter, multiply by 22.678 cm 3 mol/(L·g). Data obtained from CRC Handbook of Chemistry and Physics , 44th ed. pages 2560–2561, except for critical temperature line (31.1 °C) and temperatures −30 °C and below, which are taken from ...
1/81 (/) is correctly expressed as 1.012345679 in the preceding section, "Other mathematical curiosities", so there seems to be no valid reason to allow "about" 1.0123456789 is the "Decimal coincidences" section.
In that year, the industrial sector consumed about 42.2% of the electricity, with the residential sector consuming nearly 26.8%, the commercial and public services sectors consuming about 21.1%, the transport sector consuming nearly 1.8%, and the other sectors (such as agriculture and fishing) consuming nearly 8.1%.

[1] It has a diameter of 0.955 inch (24.26 mm) and a thickness of 0.069 inch (1.75 mm). Its current version is composed of two layers of cupronickel (75% copper, 25% nickel) clad on a core of pure copper. [2] With the cupronickel layers comprising 1/3 of total weight, the coin's overall composition is therefore 8.33% nickel, 91.67% copper.
