How long is 1 Sol on Mars?

Could you please enlighten me on a matter related to Martian time measurement? I'm curious to know how we can translate our understanding of time on Earth to Mars. Specifically, I'm wondering how long does one Sol, which I understand is the Martian equivalent of our Earth day, actually last? Is it significantly different from a day on our planet, and if so, how does this affect the way Mars explorers and scientists might measure and plan their activities? Thank you for clarifying this concept for me.
