In the Rules of Nines, what percentage is assigned to the front and back of the torso?

Explanation:
In the Rule of Nines, the trunk is split into two equal halves: the front (anterior trunk) and the back (posterior trunk). Each half accounts for 18% of total body surface area. So the front of the torso is 18%, and the back of the torso is also 18%. If both were burned, the entire torso would be 36%. The other numbers don’t match the division of the trunk: 9% is for a single limb or the head, and 4.5% isn’t used in this scheme.
