Minecraft Joules (MJ) are the energy units of all BuildCraft Engines and Machines. This is a list for reference about the MJ production and consumption of the different Engines and Machines.
NOTE: Minecraft Joules are not to be confused with Energy Units, which is the Industrial Craft 2 equivalent. Please be aware that Buildcraft engines and other machines will not work with EU, and vice versa. You will need an Energy Link to convert EU to MJ or an Engine Generator to convert MJ to EU.

Filler[]
The filler has a 40% chance of not placing a block but still using the energy it would have.
Quarry[]
The quarry's mechanical arm moves at a speed dependent on how much energy it is able to draw from the internal storage. The exact formula for calculating movement speed is 0.015 + Energy Per Action / 200, meaning it will move at a minimum of 0.015 meters per tick, to a max of 0.015 + 9/200 = 0.06 meters per tick. In comparison, this is approximately the same speed as sneaking.
While digging, the quarry tries to perform an action every tick, which is why the energy per action is lower than other machines.
