Is there an equation to convert mass to volume assuming a negligible gravitational effect. So say 1 micro gram occupies a particular volume.
sophiecentaur said:The relationship between mass and volume is called the Density (look it up). Density varies from substance to substance. Gravity doesn't come into it unless you are dealing with a substance that is compressible under its own weight (say air).
But a Planck volume is not 1 m3, it is (1 Planck length)3, or about 4 × 10-105 m3.hubble_bubble said:... I was thinking I could scale them up somehow to say make 1 Plank volume equal to 1 cubic metre for convenience and then derive the other units from that.
russ_watters said:I think the idea was to divide it by 4x10-105 to make it easier to work with.
russ_watters said:You aren't really explaining what you are trying to do, so I have no idea what the issue is. Perhaps you need to be working with the equations without plugging in the values?
russ_watters said:Yes, if you don't want to deal with ugly values, working with equations can avoid that.
russ_watters said:And yes, you can certainly find tables of densities online. However, be aware that density is a macro phenomenon that depends on the arrangement of the atoms. There is not one single density for an element. This probably means that what you are seeking to do isn't possible.
Mass to volume conversion is a process in which you convert the mass of a substance into its equivalent volume measurement. It is used in various scientific fields, such as chemistry and physics, to accurately measure and compare the amount of a substance.
The formula for mass to volume conversion depends on the substance and its physical state. For example, the formula for converting the mass of a solid substance to its volume is density = mass/volume. On the other hand, the formula for converting the mass of a liquid substance to its volume is volume = mass/density.
Mass to volume conversion is important in science because it allows for accurate and standardized measurements of substances. It also helps scientists compare and analyze the properties of different substances, which is crucial for conducting experiments and making scientific discoveries.
Mass is typically measured in grams (g) or kilograms (kg), while volume is measured in milliliters (mL) or cubic centimeters (cm3). However, depending on the substance and its properties, other units may be used, such as pounds (lbs) for mass and liters (L) for volume.
To perform a mass to volume conversion, you need to know the mass of the substance and its density. Then, you can use the appropriate formula to calculate the volume. Make sure to use the correct units and conversions, if necessary, to ensure accurate results.
