Calculation of hours spent using COCOMO 2

How to calculate development time (hours) using COCOMO2? I am trying to calculate the time (hours) that a programmer will spend on a programming project using COCOMO2. Here is what I have, but I'm not sure if this is correct. I would prefer to calculate this manually instead of using an online calculator. Any help would be really appreciated:

Formula: PM = Coefficient * KLOC ^ (increased to 1.01 + 0.01 * the sum of 5 scale factors) * product from 17 cost drivers

Months of Man (PM) =?
Coefficient = 2.5 ?? (team of mixed experience, is this coefficient correct?)
Thousand lines of code (KLOC) = 100
Sum 5 Scale factors = PREC 2.43 + PMAT 2.73 + TEAM 3.95 + FLEX 3.64 + RESL 3.38 = 16.13
Product from 17 scale factors = 17.32

Therefore, 2.5 * 100 ^ (1.01 + 0.01 * 16.13) * 17.32 = 9529.9

Is this correct 9529.9? On which block is it measured? I am trying to get the hours spent on a project.
