A cell reference is the address of the cell like A1 or B20 or C45. A cell value is what is actually in the cell. So in cell A1 you could have 23, in B20 you could have 190 and in C45 you could have 3461.
Not exactly. A cell address purely refers to the location of the cell. C5 is a cell address. In referring to a cell, you can refer to it in 4 different ways. C5, is a relative reference. $C5 and C$5 are mixed references. $C$5 is an absolute reference. A relative reference and a cell address are therefore done in the same way. In the context of a formula, we are referring to cells, so we can talk about cell references and in particular when we are using the words relative, mixed and absolute. See the related question below.
Cell content is what is stored in the cell (like a number) and cell reference is the address of the cell (like A12).
Although Excel checks that the formula has the correct structure, it does not check that the formula contains the correct values or cell references.
Cell references are the addresses of cells and values are what are contained in the cell. So A3 could be a cell reference and the number 42 could be a value in the cell.
Relative cell references and some mixed cell references will change when a formula is copied.
relative cell address
Cell references in Excel are typically referred to as the unique identifier that points to a specific cell or range of cells within a worksheet. They are used in formulas to perform calculations or manipulate data based on the content of those cells.
It formats the values.
In order to do formulas that use values in cells, you need to be able to refer to those cells in the formulas. That is what a cell reference does. You can then create formulas that can be copied quickly and be used for any values that may appear in the cells. As much as possible cell references, rather than values, should be used in formulas.
It contains relative cell references.
It would be a formula that includes absolute references in cells. When such a formula is copied, those cell references will not change. An absolute cell reference includes cell references with two dollar signs in them, like: $A$2.
You would first need to know how the fat in milk is calculated and have a formula for it. You would need to know what values are needed to do it. Then you would need to get the values you need and enter them into cells in the spreadsheet. Using these cell references to build your formula, you could do the calculation.
If autocalculate is turned on (default setting), Excel will automatically recalculate all cell values in real time any time a referenced cell is changed.
You can do this using relative reference.
