the level of human love. (?)

An extent of (human) love

A degree of (human) love ?

when would someone use this. Can I get a snippet?

“Специалисты выяснили, каким образом можно определить степень влюблённости человека по его внешнему виду.”

So basically this means that specialists have figured out how to gauge someone’s how in love someone is by their appearance?

Yeah, but it’s just an example, basically you can figure out how “in love” someone is by the way he/she talks, looks, behaves etc. That is, yes, you can make sense of the “degree” of love, either you’re madly in love with someone, adore or it’s just a sympathy.

Thank you 🙏
