Density is mass/(volume) while weigh is mass/(gravity).
Examlpe: A ton of iron and a ton of straw weigh the same (a ton) but take up different amounts of space due to different densities.

∙ 13y agoWeight is a measure of the force of gravity, while density is the measure of mass. Density is essentially how much mass is crammed into a space. Imagine holding a pencil, now imagine holding a pencil as heavy as a car. The two pencils are the same size and dimensions, but the second is obviously more dense.

How does density vary for a component at its critical point?
For a pure component the density difference between a liquid and gas approaches zero as the critical point is approached. By definition liquid and gaseous phases are indistinguishable (meaning no difference) at the critical point.
Per meter unit weight of mild steel hollow pipes 2 mm thick?
No set answer to that, as steel pipes come in various diameters and wall thicknesses. If you want to be real accurate, they also come in various steel alloys, which do have some difference in density between them.
What is the difference between density and specific heat?
Density has dimensions of: mass/volume for example: the density of water at 4 °C is 1.000 g/cm3 Specific heat has dimensions of: energy/(mass·temperature) for example: the specific heat of water is about 1 calorie/g·°C
Does steel have a high or low density?
The Density of Low Grade SteelThe density of low grade steel is on the order of 7850 kg/m3, 78.5 kN/m3, 7.85 g/cc or 0.2836 lb/in3.
How can you calculate the weight of pipe used for slitter shaft if you take a 25 mm thick pipe with 195 mm OD and 3400 length assuming it to be MS shaft?
Calculate the volume of the outer cylinder as pi*r*r*h where pi = 3.14159, r = 195, and h = 3400. Calculate the volume of the inner cylinder with r = (195 -25) = 170. The difference between the two is the volume of MS (steel used). density = mass / volume mass = density * volume. weight = mass * gravity (= 9.8)
Distinguish between mass density and weight density?
The difference is that the mass density not effect by gravity but weight density effect by gravity. for example if mass density cotn in earth equal to 20 kg/m3 and weight density equal to 196.2 N/m3 this cotn will change the weight density in the moon but mass density not change because gravity moon diffrent to gravity earth mass density =mass/volume (no gravity) weight density= (mass * gravity)/volume (gravity)
What the difference between density and concentration?
Density is the weight per volume of a solution, while the concentration is the amount of particles/molarity per volume.
What is difference between brass and bronze?
The biggest difference between bronze and brass is the density, mass, and weight. Bronze and brass are also made of different metals.
What is the difference between surface and density?
You cannot use surface area to calculate density. Density is a calculation comparing TOTAL area and weight of an object. In short you must use the total volume of the object when calculating the density.
What is the relationship between grativy weight and density?
weight = gravity times massand weight = density times volume
What is the differnce between density and specific gravity?
density is like weight and gravity is what pulls you to the ground density is what determines weight
What is the difference between specific gravity and density?
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.
What is the difference between high and low density polyethylene?
density of HDPE
What is difference between density in air and density in vacuum?
subtract 0.0011 from the density in vac to get density in air.
What difference between density in air and density in vacuum?
subtract 0.0011 from the density in vac to get density in air.
What are the relationships between weight and density?
Given an unchanging volume, if you lower the density you will lower the weight, and the revers is true.if you lower the weight the the density would lower as well.This applies to any gravitational field if you are measuring density as a function of weight per volume.
What is the difference between a probability density curve and cummulative distribution function?
