how do I upscale A4 to A3 10 POINTS EASY ANSWER?

I'm doing a grid reference drawing from A4 printout. I'm using smooth board A3 for the actual drawing. as for the grid, the printout had a 0.5' border so therefore starting from the picture reference I've done a 10 block(width) x 15block(length grid at 2cm each. How do I now transfer this up to A3? Or does anybody know the block measurements. I really need the measurements in cm of the block length ie 2cm 3 cm etc

    Multiply each measurement by 141%. So 2cm becomes 2.82cm.
