The relationship between the torr and the millimeter of mercury is: 1 Torr = 0.999 999 857 533 699... mmHg; 1 mmHg = 1.000 000 142 466 321... Torr; The difference between one millimeter of mercury and one torr, as well as between one atmosphere (101.325 kPa) and 760 mmHg (101.3250144354 kPa), is less than one part in seven million (or less than ...
Pressure increase per millimeter of a water column at Earth mean sea level [26] 10 Pa Pressure due to direct impact of a gentle breeze (~9 mph or 14 km/h) [27] [28] [29] 86 Pa Pressure from the weight of a U.S. penny lying flat [30] 10 2 Pa
So, for example, pressure head might be written "742.2 mm Hg" or "4.2 in H 2 O at 59 °F" for measurements taken with mercury or water as the manometric fluid respectively. The word "gauge" or "vacuum" may be added to such a measurement to distinguish between a pressure above or below the atmospheric pressure.
Millimetre of water (US spelling millimeter of water) [3] is a unit of pressure. It may be defined as the pressure exerted by a column of water of 1 mm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity, so that 1 mmH 2 O (4 °C) = 999.9720 kg/m 3 × 9.80665 m/s 2 × 1 mm = 9.8063754138 Pa ≈ 9.80638 Pa, but conventionally a nominal maximum water ...
By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.
A pound is equal to 16 standard ounces, so even a small amount of gold carries a lot of value. ... This bar weighs a stunning 27.4 pounds and is worth $959,000 at the recent spot price.
For example, the freezing point of water is 0 °C and 32 °F, and a 5 °C change is the same as a 9 °F change. Thus, to convert from units of Fahrenheit to units of Celsius, one subtracts 32 °F (the offset from the point of reference), divides by 9 °F and multiplies by 5 °C (scales by the ratio of units), and adds 0 °C (the offset from the ...
