Hi Thejas,

In the Einstein Toolkit, we use, as is common in numerical relativity, units where the speed of light, c, and the gravitational constant, G, are chosen to be c=G=1. In addition, we measure mass in units of the solar mass, M_sun. 1 solar mass can be converted into a length by multiplying by G and dividing by c^2. This is then the unit of length. We can convert that into a time by dividing by c. So the unit of length and time in SI units are then

[L] = 1 M_sun*G/c^2 = 1477 m. [T] = 1 M_sun*G/c^3 = 4.93 10^-6 s.

As can be seen, the unit of length is 1 half the Scharzschild radius of a black hole with a mass of 1 solar mass. The unit if time is then the time it takes light to travel that distance.

Cheers,

Peter
