Description
Convert each resolution to the common base and return firstBaseResolution/secondBaseResolution.
Personal measurement records use resolutions, scales, reference values, and rounding rules. Resolution is a recording increment and differs from accuracy, uncertainty, and clinical agreement.
Convert each resolution to the common base and return firstBaseResolution/secondBaseResolution.
When to use this tool
Use Wearable Unit Resolution Ratio when you need one explicit measurement-record comparison or supplied calibration component.
How to use the tool and how it works
- Enter firstResolution, firstBasePerUnit, secondResolution, secondBasePerUnit. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read firstBaseResolution, secondBaseResolution, ratio. Use the output convention below.
Require positive resolutions and positive base-per-unit factors for both devices. Convert each resolution to the common base and return firstBaseResolution/secondBaseResolution.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstResolution | First Resolution | Required. Finite number; strictly above 0. |
| firstBasePerUnit | First Base Per Unit | Required. Finite number; strictly above 0. |
| secondResolution | Second Resolution | Required. Finite number; strictly above 0. |
| secondBasePerUnit | Second Base Per Unit | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| firstBaseResolution | First Base Resolution | Required. Finite number. |
| secondBaseResolution | Second Base Resolution | Required. Finite number. |
| ratio | Ratio on the numerator and denominator basis stated above. | Required. Finite number. |

}Limitations and assumptions
- Resolutions describe increments, not accuracy or uncertainty; factor identity, unit compatibility, and device suitability are supplied rather than verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
