Two astronauts, Susan and Bob, travel to Mars and begin discussing Bob's mass.

Bob: My weight on Earth is $600\text{ N}$. Mars' gravity is $2.65$ times less that of Earth's. Therefore my mass on Mars is $227\text{ kg}$.

Susan: If your weight on Earth is $600\text{ N}$, your mass on Earth is $61.2\text{ kg}$. Since Mars' gravity is $2.65$ times less that of Earth's, your mass on Mars is $2.65$ times less your mass on Earth. This means your mass on Mars is $23.1\text{ kg}$.
