1 AM = 20 RF = 125 J = 5 EU = 32 gJ 1 EU = 10 J = 0.4 MJ = 4 RF = 6.557 gJ 1 MJ = 25 J = 10 RF = 2.5 EU = 16 gJ 1 J = 0.04 MJ = 0.4 RF = 0.1 EU = 0.655 gJ 1 RF = 0.1 MJ = 2.5 J = 0.25 EU = 1.6 gJ 1 gJ = 0.065 MJ = 0.1525 EU = 1.525 J = 0.625 RF 1 AE = 0.5 EU = 2 RF = 11256 W = 5 J

1 RF = 1 FE = 1 T = 1 CF = 1 IF

To your logic, 1 FE is 1 RF, while 1 AE is 1 RF, causing 1 FE to equal 1 AE, so you can add that

You forgot about this mod's energy system.
https://www.curseforge.com/minecraft/mc-mods/hbms-nuclear-tech-mod

Also I think "AE" is "Applied Energy".

There is a mod which lets you use FE to power create mod’s shafts!

1 RPM = 1FE
16FE = 15RPM

1 RF = 1 CF
Calculated by using a Mekanism Digital Miner, letting the built-in energy buffer run down from mining (16,000 RF), then putting a full Single Battery from Actually Additions into the top-right power slot, and seeing how much power is drained from it to fill the buffer (200,000 -> 184,000 = 16,000 CF).

Micro Infinity is μI

If 1MJ = 10 RF and 1AE = 2RF then 1MJ = 5AE.

AE conversion rates are available on the official wiki listed here (1.17 and newer) and here (up to 1.16).

1 AE is not 1RF, it's actually 2 RF (As their wiki says)
So 1 AE = 5 J

There's a typo across the top, where CF is typed as CR

I created a small tool for the conversion, based on this document. Minecraft Energy Calculator: https://calculator.btwyt.com?cs=g

Hi, can you re-upload this site? It will be very helpful. Thanks!

Does anyone know the conversion rates for Powah (FE) and Tech Reborn (E)?

Heat's a vanilla power unit?

Add HE from HBM's Nuclear Tech Mod (1.7) pls

Idk but i think Extended Edition (1.12) got the same conversion rate

16 years of modded Minecraft and they still can't pick a standardized power unit...

Does anyone know the conversion rate of OP from draconic evolution?

Is it possible to edit your comments to remove the link to the malware site?
