<br>
In the Einstein Toolkit, we use, as is common in numerical relativity, <br>
units where the speed of light, c, and the gravitational constant, G, are <br>
chosen to be c=G=1. In addition, we measure mass in units of the solar <br>
mass, M_sun. 1 solar mass can be converted into a length by multiplying by <br>
G and dividing by c^2. This is then the unit of length. We can convert <br>
that into a time by dividing by c. So the unit of length and time in SI <br>
units are then<br>
<br>
[L] = 1 M_sun*G/c^2 = 1477 m.<br>
[T] = 1 M_sun*G/c^3 = 4.93 10^-6 s.<br>
<br>
As can be seen, the unit of length is 1 half the Scharzschild radius of a <br>
black hole with a mass of 1 solar mass. The unit if time is then the time <br>
it takes light to travel that distance.<br>
<br>
Cheers,<br>
