Universal gas constant Standard acceleration of gravity Standard atmospheric pressure Stefan—Boltzmann constant Boltzmann's constant Speed of light in vacuum It is an international reference pressure defined as 101.325 kPa. m6/kmol2 1 dm3/mol = 1 L/mol = 1 m3/kmol (where kmol is kilomoles = 1000 moles) Automated unit of measure converter with over 250 units, both Imperial and metric, can be converted with the convenient tool. Check the chart for more details. Torr (torr) Based on the original Torricelli barometer design, one atmosphere of pressure will force the column of mercury (Hg) in a mercury barometer to a height of 760 millimeters. Units include MPa, GPa, pounds, kilograms, psi, grams, ounces, watts, joules, and many more. 1 atm = 14.6956 psi = 760 torr. Do a quick conversion: 1 liters = 0.001 cubic meters using the online calculator for metric conversions. 1 joule (J) = 1 newton meter (Nm) 1 calorie (cal) = 4.184 joule (J) 1 kilowatt hour (kWh) = 3.6 x 10 6 joules (J) = … On the other hand, specific fuel consumption is a measure of the fuel efficiency of any engine that burns fuel to produce power, such as automobile engine (brake specific fuel consumption) or thrust, such as a jet aircraft engine (thrust specific fuel consumption).The word “brake” in the term “brake specific fuel consumption” indicates that it is … Its specific values have different definitions. Kilonewton/Square Meter : The kilonewton per square meter (kN/m2) is a non-SI unit for pressure. 1 atm = Standard Atmospheric Pressure (Imperial and USA systems of units) = 1.01325 bar = 101.325 kN/m 2 = 101.325 kPa = 760 Torr=mm Hg at 0°C/32°F = 29.92 in Hg at 0°C/32°F = 14.696 psi = 0 psig = 33.899 ft H 2 O at 4°C/39°F = 10.33 m H 2 O at 4°C/39°F = 406.8 igw at 4°C/39°F = 2116.2 lb f /ft 2 = 1.033x10 4 kp/m 2 1 kN/m2 equals 1,000 N/m2.
