For instance, let's assume you have your original number in cell A2, you wanted the normalized number in cell B2, and the metric prefix and unit name in cell C2. This is fine and good, but what if you want just the 7.3 in the cell, and then a metric prefix with a unit in an adjoining cell, such as kilograms? This is a bit more complex, but it can be done using formulas. Because of the way the cell format was entered, the portion after the E will always be a multiple of 3. Now, when you enter a number such as 7340 into the cell, Excel displays it as 7.3E+3. Thus, 43645N 43.645kN To help further, on your calculator is an 'ENG' button. If you want more, increase the number of zeros after the decimal place.) From the list of engineering prefixes on page 64 it is apparent that all. (This provides only one number to the right of the decimal place.

In the Type box, enter #0.0E+0 as your format.

In the list of format categories, choose Custom.

The Number tab of the Format Cells dialog box. Excel displays the Format Cells dialog box.

Click the small icon at the lower-right corner of the Number group.

To do this, you would follow these steps: Note that the decimal place of the number can be moved to convert scientific notation into engineering notation. For example, 10 3 would have the kilo prefix, 10 6 would have the mega prefix, and 10 9 would have the giga prefix. This is so that the numbers align with SI prefixes and can be read as such. It is possible in Excel to use a custom number format to express information in scientific notation that will normalize the display of a number to a multiple of 10^3. Engineering notation is similar to scientific notation except that the exponent, n, is restricted to multiples of 3 such as: 0, 3, 6, 9, 12, -3, -6, etc.

mol J/ (K mol) K / mL J/ (mol mL) OK, the answer is 4.6 J/ (mol mL).

Do the number calculation on the calculator (and get 4.6), and work out the final units calculation by hand on paper. Rats Now you have to do two calculations. For instance, you may need to show numeric values normalized to multiples of 10^3, such that 7340 is expressed as 7.0 is expressed as 73.4. 0.078 mol 8.314510 J/ (K mol) 298.15 K / 42.0 mL. In an engineering environment, it is not unusual to need to "normalize" numbers in some manner.
