Conversely means the opposite or the other way around.
When we use conversely, we're usually talking about two ideas that are related but work in different ways. For instance, if we say "the more you sleep, the healthier you'll be", then it's only logical to add "conversely, the less you sleep, the sicker you may get". In other words, conversely helps us contrast or compare two opposite situations. We often use it when describing cause-and-effect relationships or when talking about how things can go either way depending on the circumstances.
(often conjunctive) With a reversed relationship.
