Together with different Excel options, reminiscent of conditional formatting and information validation, engineering notation empowers customers to create visually interesting and informative spreadsheets that successfully talk information insights.
Understanding Engineering Notation
Engineering notation is a technique of expressing very giant or very small numbers in a extra concise and readable format. It’s generally utilized in scientific and engineering purposes the place giant numbers are encountered often. Engineering notation includes utilizing exponential notation, the place a quantity is expressed as a base multiplied by an influence of ten.
The Base or Scientific Notation Kind
In engineering notation, the bottom is at all times a quantity between 1 and 10. Probably the most generally used base is 10, which provides us the usual scientific notation. In scientific notation, a quantity is represented within the kind:
Quantity = Mantissa × 10^Exponent
The place:
–
Mantissa: The mantissa is the numerous digits of the quantity, which is at all times higher than or equal to 1 and fewer than 10.
–
Exponent: The exponent is an integer that signifies the facility of 10 by which the mantissa is multiplied. The exponent might be optimistic or unfavourable, relying on whether or not the quantity is bigger than or lower than 1.
| Engineering Notation | Scientific Notation | Commonplace Notation |
|---|---|---|
| 2.5E+6 | 2.5 × 10^6 | 2,500,000 |
| 1.23E-4 | 1.23 × 10^-4 | 0.000123 |
Changing Numbers to Engineering Notation
To transform a quantity to engineering notation in Excel, you need to use the ENG perform. The ENG perform takes two arguments: the quantity you wish to convert, and the variety of digits you wish to show after the decimal level.
For instance, the next components converts the quantity 123456789 to engineering notation with two digits after the decimal level:
=ENG(123456789, 2)
The results of this components is “1.23E+08”.
It’s also possible to use the ENG perform to transform numbers to scientific notation. To do that, you merely must specify the variety of digits you wish to show after the decimal level, and Excel will robotically convert the quantity to scientific notation.
For instance, the next components converts the quantity 123456789 to scientific notation with two digits after the decimal level:
=ENG(123456789, -2)

9. Use the Engineering Notation Operate
Excel doesn’t have an automated choice or shortcut to transform numbers into engineering notation. When you can apply the components, `=1.23E+06`, to manually format a quantity into engineering notation, a extra environment friendly option to implement engineering notation for a number of values is thru a customized perform. Under is the code for a customized perform that you need to use to transform numbers into engineering notation:
“`
Operate EngineeringNotation(Quantity As Double, Optionally available SignificantDigits As Integer = 2) As String
Dim Exponent As Lengthy
‘Extract the exponent
Exponent = Int(WorksheetFunction.Log10(Abs(Quantity))) + 1 ‘Add 1 to make sure the exponent just isn’t unfavourable
‘Convert the quantity to engineering notation
EngineeringNotation = Format(Quantity * 10 ^ (-Exponent), “0.” & String$(SignificantDigits, “0”) & “E+00;0.” & String$(SignificantDigits, “0”) & “E+00”)
‘Return the outcome
Finish Operate
“`
To make use of this perform, merely enter the next components within the cell the place you need the outcome to look:
“`
=EngineeringNotation(Quantity, SignificantDigits)
“`
The place:
* `Quantity` is the quantity you wish to convert to engineering notation.
* `SignificantDigits` (Optionally available) is the variety of important digits you wish to show. The default is 2.
For instance, the next components would convert the quantity 123456789 to engineering notation with 2 important digits:
“`
=EngineeringNotation(123456789, 2)
“`
The outcome can be `1.23E+08`.
10. Changing to Engineering Notation
In instances the place the numbers you enter are too giant or too small to conveniently characterize in customary notation, you’ll be able to convert them to engineering notation. This could make them simpler to learn and perceive by representing them utilizing prefixes that point out the facility of 10.
To transform a quantity to engineering notation,:
- Transfer the decimal level to the precise or left till there is just one non-zero digit earlier than the decimal level.
- Rely the variety of locations you moved the decimal level.
- For those who moved the decimal level to the precise, the multiplier can be 10 raised to the unfavourable energy of the variety of locations you moved it. For those who moved the decimal level to the left, the multiplier can be 10 raised to the optimistic energy of the variety of locations you moved it.
