## Conversion calculations in Excel

Microsoft Excel’s CONVERT Function.

Microsoft Excel is one of those great software applications that empowers us to do a lot of different things. You can create art masterpieces , convert digital photos into pixel worksheets , create a cool animation , build a flight simulator , or play a game of Tetris . If you don’t feel ambitious enough to write pages upon pages of VBA code, but still want to do something practical with the program, perhaps you want to learn how to perform different conversion calculations in Excel? In fact, CONVERSION function enables you to convert weight, distance, time, pressure, force, energy, power magnetism, temperature, volume, liquid measure, area, information, and speed measures from one unit to another. The later version of Microsoft Excel you are running the more conversions you can perform. If you are working in Excel 2003 or earlier, this function is not available on earlier versions of Microsoft Excel.

## Calculating age without DateDif function – Mission Impossible?

Calculate your age, WITHOUT using Excel’s DateDif function.

My previous post on using Excel’s DATEDIF function resulted in rather productive discussions on LinkedIn. First of all, some users are concerned that the DATEDIF function will no longer be supported in Excel and will cease to exist at some point in the future. Microsoft openly states that “this function is provided for compatibility with Lotus 1-2-3.” , and given the history of this support, I don’t see why it will be discontinued. Nonetheless, I will make an attempt to replace DATEDIF function with other functions readily available in the program. Secondly, as a reminder that English is not the only language in the world, Microsoft created “local” versions of this function. A user confirmed existence of the SIFECHA function, but the syntax to use it, involves using semicolons, instead of commas. If you are using Spanish version of Excel, you might want to try both versions:

```SIFECHA(fecha_inicial,fecha_final,unidad)
```

According to this site , remaining versions of this function include:

## Calculate your age using Excel DateDif function

Calculate your age, using Excel’s DateDif function.

During this time of the year, most of us find ourselves performing some sorts of date manipulations in Excel: running year-end reports, creating a project plan for the next year, or simply setting up a new calendar. Let’s use one of Excel’s “hidden” functions to calculate one’s age in years, months, and days.

We remember that Excel stores dates as serial numbers, in consecutive order. According to Microsoft, Day 1 fell on January 1st, 1900. Therefore, today’s date is equivalent to number 42,020 (meaning, 42,020 days passed since January 1st, 1900.) This makes it fairly easily to calculate difference between two dates [in days] by subtracting one date from another. While Excel does not support dates prior to January 1st, 1900 out of the box, if you need to work with such dates, John Walkenbach offers an Excel add in: XDate to help with this task.

## Using Nested IF Functions

Using Nested If Statements.

A reader asked me to explain logic behind the formula used in my Holiday Email post. That solution involved using multiple IF functions as arguments within another IF function, technique also known as nested IF logic. I find that the best way to use nested if functionality is through using decision trees AND Excel’s VBA syntax. Charting a decision tree will help us better understand the task at hand, and putting various conditions and the ways to handle them in writing, will prepare us to enter necessary formula in Excel.

Let’s suppose that we need to implement the following logic with 4 possible scenarios. If the value of cell 1 is string “Case 1” AND cell 2 is string “Case 2”, we need the output to be 4. If cell 1 equals “Case 1”, but cell 2 does NOT equal “Case 2”, we need the output to be 3. If cell 1 does NOT equal “Case 1” , but cell 2 equals “Case 2”, the output should be 2. Finally, if cell 1 does not equal “Case 1”, NOR cell 2 equals “Case 2”, the output is 1. Hopefully, using the decision tree below makes it easier to conceptualize these scenarios.
