Data conversion from DPM to DPSH

Answer from Diego

A colleague asks for a suggestion to convert the number of shots obtained with a 30kg dynamic penetrometer to a 73kg DPSH. I made 2 unpretentious accounts, but indicatively should address towards the solution.

Excel sheet.

The excel sheet compares the yield of the 2 instruments.Every three readings of the DPM30 the sheet makes the sum of the strokes and corrects it with the coeff. correction so as to obtain, in theory, the number of DPSH shots.
