Chemistry Question

The Entropy, delta S, is -326.32
Enthalpy, delta H, is -571.6

Now, to calculate delta G (free energy) it says it is equal to Enthalpy minus T(delta)S. She said we will use 298K for T because we work in the standard conditions. Now, in an example problem she did 298 times .14772 when the (S) Entropy was 147.72. She moved decimal place over three to the left. Why? No clue, that's what I want to know.

Always, always, always check your units. The numbers mean nothing without units attached.
