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 functions the place giant numbers are encountered often. Engineering notation entails 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 type:
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 constructive or damaging, 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 operate. The ENG operate takes two arguments: the quantity you need to convert, and the variety of digits you need to show after the decimal level.
For instance, the next formulation converts the quantity 123456789 to engineering notation with two digits after the decimal level:
=ENG(123456789, 2)
The results of this formulation is “1.23E+08”.
You too can use the ENG operate to transform numbers to scientific notation. To do that, you merely have to specify the variety of digits you need to show after the decimal level, and Excel will robotically convert the quantity to scientific notation.
For instance, the next formulation converts the quantity 123456789 to scientific notation with two digits after the decimal level:

9. Use the Engineering Notation Operate
Excel doesn’t have an computerized choice or shortcut to transform numbers into engineering notation. Whilst you can apply the formulation, `=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 operate. Under is the code for a customized operate that you need to use to transform numbers into engineering notation:
“`
Operate EngineeringNotation(Quantity As Double, Non-compulsory 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 will not be damaging
‘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 operate, merely enter the next formulation within the cell the place you need the outcome to seem:
“`
=EngineeringNotation(Quantity, SignificantDigits)
“`
The place:
* `Quantity` is the quantity you need to convert to engineering notation.
* `SignificantDigits` (Non-compulsory) is the variety of important digits you need to show. The default is 2.
For instance, the next formulation 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 signify in commonplace notation, you possibly can 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 fitting 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.
- In case you moved the decimal level to the fitting, the multiplier will likely be 10 raised to the damaging energy of the variety of locations you moved it. In case you moved the decimal level to the left, the multiplier will likely be 10 raised to the constructive energy of the variety of locations you moved it.
