Darkness is the absence of light, so it is not a physical quantity that can be measured in the same way that light can be measured. However, darkness can be quantified in terms of the amount of light present in a given space. For example, a room with no windows and no light sources would be considered darker than a room with some natural or artificial light. So while darkness itself may not be directly measurable, its effects and presence can be quantified in relation to the amount of light present. **

It ultimately depends on the individual and their personal experiences and associations with darkness. **
