Converting DC to reflectance (0-1) manually

Hi, Im new to sentinel 2 data…Currently im trying to do landcover classification using sentinel 2 data…where can i find the Ak and Es value?

I am not sure if I fully understood the question, but perhaps the following link will help you:

hi…i tried dividing the DN by the quantification value, but the result turned out to be black in color only…should i change the 32 bit image into any certain bit?

If I understand it correctly, Ak (the MSI absolute calibration) and Es (the equivalent extra-terrestrial solar spectrum) are values taken from the Level-1B, and accounted for in the Level-1C processing (TOA conversion).

Cheers
