How do you convert specific gravity to specific weight?
How do you convert specific gravity to specific weight?
For example, the specific gravity of 0.84 corresponds to the density of 840 (0.84 x 1000) kg/cubic meters. Multiply the density by the acceleration of gravity (9.81) to calculate the specific weight. In our example, the specific weight is 840 x 9.81 = 8,240.4.
How do you convert specific gravity?
Density of the fluid ÷ Density of water = Specific Gravity The specific gravity will tell us whether the fluid will float or sink in the water. If it is higher than 1 it will sink in water; lower than 1 and it will float.
Why is density measured at 15 C?
Since the density of a liquid varies as its temperature changes, the scale is adjusted to a certain temperature, usually about 15 degrees C., at which determinations must be made. Its scale is adapted to liquids heavier or lighter than water.
How do you calculate weight using mass?
Mass does not change with location. To find an object’s mass using its weight, the formula is Mass equals Weight divided by the Acceleration of Gravity (M = W ÷ G). Convert the weight measured in pounds to the equivalent in Newtons.
Can you convert SG to density?
Converting a specific gravity into a density is as simple as multiply the SG by the reference density for which it was based. In most cases, this is the density of water, and therefore your multiply the SG by 1 to yield your density in g/cm^3.
How do I find the mass of an object?
Divide the object’s weight by the acceleration of gravity to find the mass. You’ll need to convert the weight units to Newtons. For example, 1 kg = 9.807 N. If you’re measuring the mass of an object on Earth, divide the weight in Newtons by the acceleration of gravity on Earth (9.8 meters/second2) to get mass.
How do you measure body mass?
Body Mass Index is a simple calculation using a person’s height and weight. The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared.
