## INTRODUCTION

*In any of the application or reports, we are preparing, as situation might arise when we need to change one unit to other. e.g. gram into ounce, centimeter into feet etc.*

*So we got a function to do all this for us known as CONVERT FUNCTION.*

*CONVERT FUNCTION is found under the ENGINEERING FORMULAS section under FORMULAS TAB.*

*This function gives us a wide variety of options.*

*In this article we’ll see the different styles of usage of CONVERT FUNCTION and find out the different options available with this function.*

*After that we’ll look at a fully described example to grasp the functionality of this function properly.*

## PURPOSE OF CONVERT FUNCTION IN EXCEL

**CONVERT FUNCTION converts one measurement system to other.**

For example, we have different kinds of measurement system such as MKS , fps etc. MKS is meter, kilogram , second whereas fps is foot, pound , second.

So many times we come across a situation when we need to convert these values from one system to another.

The main reason for this is the presence of different popular usages of these measurement among different societies.

e.g. In many countries, if you ask somebody’s weight, he or she’ll answer in pounds, whereas in some countries, they’ll answer in KG.

We can do these conversion manually too, but why would we when we have such a good function with us to make our task easier.

## PREREQUISITES TO LEARN CONVERT FUNCTION

THERE ARE A FEW PREREQUISITES WHICH WILL ENABLE YOU TO UNDERSTAND THIS FUNCTION IN A BETTER WAY.

- Basic understanding of how to use a formula or function.
- Basic understanding of rows and columns in Excel.
- A bit understanding of the measurement systems will help in this, because at least we need to know about the conversion, from this to that. But even if you don’t know, you can always refer here.
- Of course, Excel software.

## SYNTAX: CONVERT FUNCTION

**The Syntax for the function is**

**=CONVERT(NUMBER, OLD_UNIT, NEW_UNIT)**

**NUMBER **is the number which needs the unit conversion

**OLD_UNIT **the present unit which is to be converted

**NEW_UNIT **the new unit which appears after conversion

## EXAMPLE:CONVERT FUNCTION IN EXCEL

### DATA SAMPLE

Let us take a few examples to try our newly learnt function.Here is the data which will be converted to the new unit system using the CONVERT FUNCTION.We’ll try a few main conversions although the system is same for all . The comprehensive list is given above in the table.

NUMBER | OLD UNIT | NEW UNIT |

1 | TON | GRAM |

1 | MILE | METER |

1 | gram | POUND |

1 | YEAR | DAYS |

1 | HP | WATT |

1 | CELCIUS | FAHRENHEIT |

1 | GALLON | LITER |

### STEPS TO USE CONVERT FUNCTION

When we need to convert one unit to another, such as kilogram to pound or foot to meter etc.we can use the convert function .

We have given different examples to use convert function above.The number is given and the from unit and to unit are given.

We use the following generalized formula

=convert(number to be converted, “old measurement system”,”new measurement system”)

The output will be as per the new measurement system.NOTE: The codes for the old and new system are case sensitive which means

meter is m and not M.And all the codes should be put in an “”.
