Use a calculator, conversion table (pdf) or equation to convert the power units. Here is a short conversion table:

dBm

Watts

0 .001
15 .032
24 .250
27 .500
30 1.000
36 4.000

The equation is:

dBm = 10 * (log (1000 * P))

P = Power in Watts

1000mW = 1 Watt

Note, doubling the wattage increases dBm by 3. Here is a more comprehensive tutorial on Using and Understanding Decibels.
