Kj to kcal and kcal to kj converter
I show you how to convert kJ to kcal and kcal to kJ using the Microsoft Excel application.
Method 1. Convert using simple division
4.184 is the crucial number here. To convert kJ to kcal, you need to just divide by 4.184. Similarly, to convert kcal to kJ, you need to multiply by 4.184.
Method 2. Conversion using CONVERT Excel function
The CONVERT function automatically converts the value based on the specified input and output units, which eliminates the need for a separate conversion factor or formula. This method is more efficient and less prone to errors, as the conversion is handled by the built-in function in Excel.
=CONVERT(cell,”unit1″,”unit2″)
Method 3. Convert using VBA code
This VBA code will ask you how many kJ you want to convert to kcal:
Function ConvertKJToKcal(kj As Double) As Double
ConvertKJToKcal = kj * 0.239006
End Function
Sub ConvertKJToKcalMain()
Dim kj As Double
Dim kcal As Double
kj = InputBox("Enter the number of kilojoules (kJ) to convert to kilocalories (kcal):")
If IsNumeric(kj) Then
kcal = ConvertKJToKcal(kj)
MsgBox kj & " kilojoules (kJ) is equal to " & kcal & " kilocalories (kcal)", vbInformation, "Kilojoules to Kilocalories Conversion"
Else
MsgBox "Invalid input! Please enter a valid number.", vbExclamation, "Error"
End If
End Sub
The custom functions in the Visual Basic module handle the conversion by applying the appropriate formula, which makes the conversion process easier and more efficient. This method also allows you to modify the conversion formulas if needed, by simply editing the code in the module.
Method 4. Convert kJ to BTU and kcal to BTU.
1 BTU is equal to 0.0009478 kJ or 0.000239 kcal, making it easy to calculate. Luckily, there is an Excel formula which converts kJ to BTU and kcal to BTU.
=cell*0.0009478 for kJ to BTU
=cell*0.000239 for kcal to BTU
It will convert 1000 kJ to 0.9478 BTU and 1000 kcal to 0.239 BTU.
