A newton is equal to 1 kg⋅m/s 2, and a kilogram-force is 9.80665 N, [3] meaning that 1 kgf/cm 2 equals 98.0665 kilopascals (kPa). In some older publications, kilogram-force per square centimetre is abbreviated ksc instead of kg/cm 2 .
The Knudsen number is a dimensionless number defined as =, where = mean free path [L 1], = representative physical length scale [L 1].. The representative length scale considered, , may correspond to various physical traits of a system, but most commonly relates to a gap length over which thermal transport or mass transport occurs through a gas phase.

The boiler was in two parts: the main, rear part, was a water tube boiler pressed to 60 kgf/cm 2 (5.88 MPa; 853 psi) (a conventional boiler was limited to 25 kgf/cm 2 or 2.45 MPa or 356 psi). The forward part was a conventional fire-tube boiler pressed to 20 kgf/cm 2 (1.96 MPa; 284 psi) and served as a feed-water heater.
(However, PE only dissolves at temperatures well above 100 °C.) Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2, and thus ethyl acetate is likely to be a good solvent. Nylon 6,6 has a solubility parameter of 13.7 cal 1/2 cm −3/2, and ethanol is likely to be the best solvent of those tabulated. However, the latter is polar ...
The SI unit for specific strength is Pa⋅m 3 /kg, or N⋅m/kg, which is dimensionally equivalent to m 2 /s 2, though the latter form is rarely used. Specific strength has the same units as specific energy , and is related to the maximum specific energy of rotation that an object can have without flying apart due to centrifugal force .
The first variant, called the T 1, emerged from a joint project with the firm of Krauss in their railway company's own workshop. The 12 locomotives built between 1871 and 1873 belonged to the few engines that were developed specifically for the Oldenburg railways. They had a boiler pressure of 98.1 kN and maximum permitted speed of 40 km/h.
It is not accepted for use with the International System of Units (SI) [1] and is deprecated for most uses. [ citation needed ] The kilogram-force is equal to the magnitude of the force exerted on one kilogram of mass in a 9.806 65 m/s 2 gravitational field ( standard gravity , a conventional value approximating the average magnitude of gravity ...
