So what we know is that powerlevel is calculation of total power output of a person. That inclued lifting.
So Goku SSJ in Namek Saga had 180.000.000 Power level (PL).
So a normal person in DBZ, like a redneck with the gun had 5 power level, now let's be generous and put it to 10 since the redneck was fat and the gun wasn't much, since Raditz just cought the bullet with 1200 Power level. A soldier would have 10 power level. And he would lift around 200 kilos near maximum(or 1/5 ton). So based on this comparison here Goku at that moment could lift 3600000 tons. (3.6 million tons)
Now Goku when he goes Masterd Super Saiyan in Cell Saga, become 20 times stronger. That means 72000000 tons.
As SSJ2 he becomes 40xSSJ1, and 2xMastered SSJ1. That number is 144.000.000 tons.
As SSJ3 just 4x 144.000.000=576.000.000 tons. (575 million tons)
Now this is speculation, but a SSJ Blue Kaioken Goku i think could lift 43200000000 tons. (43.2 billion tons)
In his MUI (Mastered Ultra Instinct) techqniue, maybe 15x that of SSJ Ble Kayo-but this is pure speculation.
If you want a speed or power (velocity x force) for Goku, these might be much greater numbers.
