瓦特(W) 转 分贝毫瓦(dBm), 功率 conversion calcula转r.
Enter the 功率 in watts and press the 转换 but转n:
dBm 转 watts conversion calculator
The 功率 P(dBm) in dBm is equal 转 10 times the base 10 对数 of 1000 times the 功率 P(W) 以瓦特(W)为单位除以1瓦特(W)：
P(dBm) = 10 log10( 1000 × P(W) / 1W) = 10 log10( P(W) / 1W) + 30
所以
1W = 30dBm
转换 20 watts 转 dBm:
P(dBm) = 10 log10(10000W) = 43.0103dBm
