With compressive force counted as negative tensile force, the rate of change of the tensile force in the direction of the g-force, per unit mass (the change between parts of the object such that the slice of the object between them has unit mass), is equal to the g-force plus the non-gravitational external forces on the slice, if any (counted ...
A force capable of giving a mass of one kilogram an acceleration of one metre per second per second. [32] = 1 N = 1 kg⋅m/s 2: ounce-force: ozf ≡ g 0 × 1 oz = 0.278 013 850 953 781 25 N: pound-force: lbf: ≡ g 0 × 1 lb = 4.448 221 615 2605 N: poundal: pdl ≡ 1 lb⋅ft/s 2 = 0.138 254 954 376 N: short ton-force: tnf [citation needed] ≡ ...
The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
the heat at which water boils vehemently (the temperature at which water begins to boil is given as an additional value in the description, as 33) 40: melting point of an alloy of one part lead, four parts tin and five parts bismuth 48: 3: melting point of an alloy of equal parts of bismuth and tin 57: 3 + 1 ⁄ 4
The saturated vapor pressure over water in the temperature range of −100 °C to −50 °C is only extrapolated [Translator's note: Supercooled liquid water is not known to exist below −42 °C]. The values have various units (Pa, hPa or bar), which must be considered when reading them.
In unit systems where force is a derived unit, like in SI units, g c is equal to 1. In unit systems where force is a primary unit, like in imperial and US customary measurement systems , g c may or may not equal 1 depending on the units used, and value other than 1 may be required to obtain correct results.

The heat required to raise the temperature of 0.239 g of water from 0 °C to 1 °C. [16] The kinetic energy of a 50 kg human moving very slowly (0.2 m/s or 0.72 km/h). The kinetic energy of a 56 g tennis ball moving at 6 m/s (22 km/h). [17] The food energy (kcal) in slightly more than half of an ordinary-sized sugar crystal (0.102 mg /crystal).
Nayar et al. correlated the data with the following equation = (+ +) where γ sw is the surface tension of seawater in mN/m, γ w is the surface tension of water in mN/m, S is the reference salinity [40] in g/kg, and t is temperature in degrees Celsius. The average absolute percentage deviation between measurements and the correlation was 0.19% ...
