Converting 50 watts to dbm results in approximately 16.9897 dBm.
Table of Contents
This conversion means that 50 watts of power is equivalent to about 16.99 decibels relative to 1 milliwatt. The calculation involves converting watts into milliwatts first, then applying the logarithmic formula to express the power level in decibels, which is a common way to compare power levels in electronics and radio communications.

Conversion Formula
To convert watts to dbm, the formula is 10 times the base-10 logarithm of power in milliwatts. Since 1 watt equals 1000 milliwatts, the formula becomes: dbm = 10 * log10(watts * 1000). This works because decibels are logarithmic, showing the ratio of power levels relative to 1 milliwatt. For example, for 50 watts: dbm = 10 * log10(50 * 1000) = 10 * log10(50000) ≈ 10 * 4.69897 ≈ 46.9897.
Conversion Example
- Convert 10 watts to dbm:
- Multiply by 1000: 10 * 1000 = 10,000 milliwatts.
- Calculate log10 of 10,000: log10(10,000) = 4.
- Multiply by 10: 10 * 4 = 40 dbm.
- Result: 10 watts equals 40 dbm.
- Convert 1 watt to dbm:
- 1 * 1000 = 1000 milliwatts.
- log10(1000) = 3.
- 10 * 3 = 30 dbm.
- Result: 1 watt equals 30 dbm.
- Convert 0.5 watts to dbm:
- 0.5 * 1000 = 500 milliwatts.
- log10(500) ≈ 2.69897.
- 10 * 2.69897 ≈ 26.9897 dbm.
- Result: 0.5 watts equals approximately 26.99 dbm.

Conversion Definitions
Watts: A measurement of power indicating the rate of energy transfer or conversion per second, used in electrical and electronic contexts to quantify power output or consumption.
dbm: A logarithmic unit expressing power relative to 1 milliwatt, calculated as 10 times the base-10 logarithm of power in milliwatts, used widely in radio, telecommunications, and audio systems to compare power levels.
Conversion FAQs
How do I convert watts into dbm manually?
Multiply watts by 1000 to get milliwatts. Then, calculate the base-10 logarithm of this number, and multiply by 10 to get dbm. For example, for 50 watts: 50*1000=50000; log10(50000)=4.69897; 10*4.69897=46.9897 dbm.
Why is dbm used instead of watts in radio systems?
dbm provides a logarithmic scale that makes it easier to handle large variations in power and compare different levels. It simplifies calculations involving gains and losses, and aligns with how humans perceive signal strength changes.
What is the significance of 0 dBm in power measurements?
0 dBm represents a power level of exactly 1 milliwatt. It serves as a reference point; power levels above 0 dBm are greater than 1 milliwatt, and those below are less. It helps standardize measurements across different systems and devices.
