Decibel-milliwatts (dBm) go vata (W) , áireamhán tiontaithe cumhachta agus conas a thiontú.
Decibel-milliwatts (dBm) go vata (W) , áireamhán tiontaithe cumhachta .
Iontráil an chumhacht i dBm agus brúigh an cnaipe Tiontaigh :
Áireamhán tiontaithe Watts go dBm ►
Tugtar an fhoirmle do chomhshó cumhachta dBm go vata:
P (W) = 1W ⋅ 10 ( P (dBm) / 10) / 1000 = 10 (( P (dBm) - 30) / 10)
Tiontaigh 43dBm go vata:
P (W) = 1W ⋅ 10 (43dBm / 10) / 1000 = 19.9526W
