如何以 MB 为单位计算 base64image 字符串大小？

Question

I am taking a picture and i am converting it into Base64 string. And i am able to calculate the size of the picture in KB. I need to know the formula to calculate the size in MB. Please clarify.

The below code works fine for calculating size in KB.

function onCameraClick() {
      var base64Val = kony.convertToBase64(frmImageSize.camCamera.rawBytes);
      var imageSizeinKB = base64Val.length*0.75 )/1024;        
}

Answer 1

For your reference:
1024 bytes = 1 KB
1024 KB = 1 MB
1024 MB = 1 GB
1024 GB = 1 TB

So if you have arrived result in KB, to get the result in MB please divide it by 1024.

Result in MB = result in KB/1024.
