So i will calculate the power level of MUI Goku today.
1. The Multiplier
First, we need to calculate the MUI multiplier. Thankfully, V&J Reviews's chart can help us here!
We already know the multiplier of SSJ 1, 2 and 3. But SSG's and SSB's multipliers are unknown. V&J said the multipliers of both are 20,000x Base for SSG, and 1,000,000x Base for SSB. But we can figure out UI's multiplier, by using this formula:
UI's multiplier = SSB's multiplier x (((UI's vaule in V&J's chart - SSB's vaule in V&J's chart) - (SSB's vaule in V&J's chart - SSG's vaule in V&J's chart)) x 50)
So we input the vaules here:
UI's multiplier = 1,000,000 x (((1157 - 565) - (565 - 250)) x 50)
And we find out that UI's multiplier is 13,850,000,000x Base.
MUI's multiplier is impossible to exactly calculate using this chart, so lets assume that its 250 chart points stronger than Jiren.
So we input the vaules here, again:
MUI's multiplier = 13,850,000,000 x ((1581 - 1331) - (1331 - 1157))
And we find out that MUI's multiplier is 1,052,600,000,000x Base.
2. The Power Level
Now, we will calculate the power level of MUI Goku.
Its simple, lets just multiply his base power level by MUI's multiplier (I will be using 150,000,000 for his base):
150,000,000 x 1,052,600,000,000 = 157,890,000,000,000,000,000
So 157,890,000,000,000,000,000 (157.89 quintillion) is MUI Goku's power level.
3. What if SSBKKx20 was used with MUI?
So again, we just multiply:
157,890,000,000,000,000,000 x 20,000,000 = 3,158,700,000,000,000,000,000,000,000
So, we find out that SSBMUIKKx10 Goku's power level is a staggering 3,158,700,000,000,000,000,000,000,000 (2.7423 octillion)!
