The conversion of 700 watts to dbw results in approximately 28.45 dBW.
To convert watts to decibel-watts (dBW), you take 10 times the base-10 logarithm of the power in watts. This calculation helps express power levels on a logarithmic scale, which is useful for comparing very large or small power values more easily.
Conversion Result
700 watts is equal to approximately 28.45 dBW.

Conversion Formula
The formula to convert watts to dbw is P(dBW) = 10 * log10(P(watts)). This works because decibels use logarithms to compress large ranges of power into manageable numbers, making it easier to compare different power levels. For example, 700 watts: log10(700) ≈ 2.845, so 10 * 2.845 ≈ 28.45 dBW.
Conversion Example
- Convert 500 watts to dbw:
- Calculate log10(500) ≈ 2.698
- Multiply by 10: 10 * 2.698 ≈ 26.98 dBW
- Convert 100 watts to dbw:
- Calculate log10(100) = 2
- Multiply by 10: 10 * 2 = 20 dBW
- Convert 1000 watts to dbw:
- Calculate log10(1000) = 3
- Multiply by 10: 10 * 3 = 30 dBW
- Convert 50 watts to dbw:
- Calculate log10(50) ≈ 1.699
- Multiply by 10: 10 * 1.699 ≈ 16.99 dBW
- Convert 700 watts to dbw:
- Calculate log10(700) ≈ 2.845
- Multiply by 10: 10 * 2.845 ≈ 28.45 dBW

Conversion Definitions
Watts
Watts (W) measure the rate of energy transfer or power, representing how much work is done over time. In electronics, it quantifies the power output or consumption of devices, with higher watts indicating more energy flow or higher power levels.
dbw
Decibel-watts (dBW) is a logarithmic unit expressing power relative to one watt. It simplifies large power differences, making it easier to compare, especially in radio, audio, and telecommunications, where power levels can vary widely.
Conversion FAQs
How do I know what dbw corresponds to 700 watts?
Use the formula: dbw = 10 * log10(700). Calculating this gives approximately 28.45 dBW, indicating how loud or powerful 700 watts is relative to one watt.
Why is logarithmic scale used in power conversions?
Logarithmic scales compress large ranges of power into manageable figures, making it easier to compare vast differences in power levels without dealing with unwieldy numbers, especially in telecommunications or audio systems.
Can I convert watts to dbw manually?
Yes, by calculating 10 times the base-10 logarithm of the watt value. For example, for 700 watts, log10(700) is approximately 2.845, and multiplying by 10 results in about 28.45 dbw.
What is the significance of a higher dbw value?
A higher dbw value indicates a greater power level, meaning a more powerful signal or output. For example, 30 dbw is stronger than 20 dbw, showing more energy being delivered or transmitted.
