How to Multiply Column by a Constant in Excel

To multiply a column by a constant in Excel, you can use a simple formula that multiplies the desired cell by the constant value. Here's how to do it:

1. Open Excel and create a new worksheet or open an existing one containing the data you want to multiply.
2. In an empty cell, type the constant value you want to multiply with the column values.
3. Click on a new empty cell where you want the result to appear. This cell will be the starting point for the multiplied column.
4. Type the formula =A1*$B$1, where A1 is the first cell of the column you want to multiply, and $B$1 is the absolute cell reference containing the constant value. You can change A1 and $B$1 to match your specific column and constant cell.
5. Press Enter to see the result of the multiplication in the selected cell.
6. To apply the formula to the entire column, click on the cell with the result, and move your cursor to the bottom-right corner of the cell until you see a small cross icon.
7. Click and drag the cross icon down the column to fill the formula for the rest of the cells.

Example

Here's an example to help illustrate the process:

1. Assume you have data in column A (from A1 to A5) and you want to multiply each value by a constant, say 3.
2. In an empty cell, say B1, type the constant value 3.
3. Click on cell C1 where you want the result of the first multiplication to appear.
4. Type the formula =A1*$B$1 in cell C1 and press Enter.
5. Now you should see the result of the multiplication (A1 * 3) in cell C1.
6. Click on cell C1, move your cursor to the bottom-right corner of the cell until you see a small cross icon, then click and drag the cross icon down to C5 to fill the formula for the rest of the cells.
7. Column C will now contain the multiplied values of column A by the constant 3.
