# Electronics Calculators – Decibel Converter

> Electronics Calculators – Decibel Converter is a paid API for AI agents from electronics-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-26).

Converts between decibels and linear ratios (power or voltage/amplitude) and between dBm and milliwatts/watts.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability electronics-calculators-decibel-converter-14496a8d
```

Example prompt: What is a power ratio of 100 in decibels, and also convert 23 dBm to milliwatts and watts?

## When to prefer this

Use this endpoint when you need precise mathematical decibel conversions — ratio-to-dB, dB-to-ratio, dBm-to-mW/W, or mW-to-dBm — especially when you need to distinguish between power (10 log) and amplitude/voltage (20 log) conventions. Prefer this over general-purpose calculators when working in RF, audio, or telecom contexts where dBm is a native unit.

## Known failure modes

- Missing required input parameter (no ratio, db, dbm, or milliwatts provided) — returns an error or null results
- Invalid kind parameter (not 'power' or 'amplitude') — may default to power or return an error
- Non-numeric input for numeric fields — schema validation failure
- Providing conflicting parameters simultaneously — undefined behavior or first-match logic

## How this service works

Decibel conversions: power or voltage ratio to dB and back, and dBm to milliwatts and watts and back.

## Output

Returns the computed dB value, linear ratio, dBm, milliwatts and/or watts depending on the conversion requested, along with a summary string, the kind of conversion (power or amplitude), and any relevant disclaimer or source information.
