WebdBm to watts conversion calculator How to convert watts to dBm. The power P (dBm) in dBm is equal to 10 times the base 10 logarithm of 1000 times the power P (W) in watts (W) divided by 1 watt (W): P (dBm) = 10 ⋅ log 10 ( 1000 ⋅ P (W) / 1W) = 10 ⋅ log 10 ( P (W) / 1W) + 30. so. 1W = 30dBm. Example. Convert 20 watts to dBm: WebDecibels are used to represent the ratio of two quantities of power: db = 10 log P1/P0 . In the case of dbm the reference power P0 is 1 milliwatt : dbm = 10 log P1/1mw. Inverting this equation gives the power in terms of the reference power: P1= P010db/10. In the case of dbm the equation is P1= 1mw·10dbm/10.
