WebSpecific gravity (SG) is the ratio between the density of a substance and the density of water. If the temperature is not specified, it is assumed to be water at 3.98ºC and therefore has a density of 0.999972 g/cm 3 or 999.972 kg/m 3. … WebMass is measured in kilograms (kg). Weight is a force due to the pull of gravity on an object. Weight is a force ... weight W in N = mass m x gravitational field strength g. W = mg. W = weight in N.
WebWeight is a force that acts at all times on all objects near Earth. The Earth pulls on all objects with a force of gravity downward toward the center of the Earth. The magnitude of the force of gravity can be found by multiplying the mass m m of the object by the magnitude of the acceleration due to gravity g=+9.8 \dfrac {\text m} {\text { s}^2 ...
