Converting light intensity values

Hi everyone,

I have a question in regards to light intensity values. I have a default value of 1277LUX. How do I convert this value so it displays correctly in UE in candela? All I see in UE is candela, but can we use LUX or lumens in UE as well? Any and all tips are greatly appreciated.

Project Settings > Engine > Rendering > Default Settings > Light Units:
(unitless)
(candelas)
(lumens) <—
