K2-18 b is located 124 light-year from earth. One (1) light year is about 6 trillion US (statute) miles.

How many years is a light-year?
What Is a Light-Year? | NASA Space Place –
For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km).

So at 124 light years away from earth and one (1) light year is 6 trillion miles, the planet is 744 trillion miles from Earth.
