I only know about the 'gram'. Is there another SI mass unit? If so, I submit it must be very elementary, perhaps a single free neutron.
Two common units for mass are kilograms and grams
A kilogram is a unit of mass. A centimetre is a unit of distance. The two units measure two different things and are therefore incompatible.
Density = Mass/Volume. Conversion between units will depend on what the two units are.
Grams and Kilogarms
You can't.You are trying to convert measurements of two different aspects of things:grams (g - in this case prefixed by kilo- to make kg) are a measure of mass (roughly how heavy something is); whereaslinear feet are a measure of length (how long something is).
The mass would not change, only the numbers describing the amount of mass would change.
Two common units for mass are kilograms and grams
There is only ONE defined unit for mass in the SI, the kilogram. Other variants are commonly used for convenience, the gram and the tonne, but the kg is the base unit. Check out SI with your favourite search engine.
Yes, the mass of an iron atom is different from the mass of a copper atom. The mass of an iron atom is approximately 56 atomic mass units, while the mass of a copper atom is approximately 63.5 atomic mass units. Therefore, there is a difference of about 7.5 atomic mass units between the two.
A kilometre is a unit of length. A milligram is a unit of mass. The two units measure two different things.
A kilometre is a unit of length. A milligram is a unit of mass. The two units measure two different things.
These are two different units of measure (volume and weight/mass) that do not convert to one another.
There is no answer to your question, because you are giving units for two different things, mass and heat or energy.
these two units lie in different categories mass and length .It cannot be converted to each other.
because capacity is mass and also amount of liquid
The mass decreases by 4 units and the atomic number by two units.
Mass and weight are two different things: you cannot measure the mass of your weight. That is like talking about the temperature of your height - it makes no sense.
