Description
Convert spatial cycles per length to angular wavenumber.
Conversion direction matters for reciprocal and logarithmic quantities. Frequencies, periods, phase coordinates and reference ratios use explicit origins, sign policies and denominator units, rather than a single ordinary length or time multiplier.
Convert spatial cycles per length to angular wavenumber.
When to use this tool
Use Angular Wavenumber Spatial Frequency Factor when converting the stated reciprocal, angular, phase or logarithmic convention.
How to use the tool and how it works
- Enter cyclesPerLength. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read radiansPerLength. Use the output convention below.
Convert spatial cycles per length to angular wavenumber. radiansPerLength = 2*pi*cyclesPerLength.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| cyclesPerLength | Cycles Per Length | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| radiansPerLength | Radians Per Length | Required. Finite number. |

}Limitations and assumptions
- The length unit is preserved and sign can represent direction; this is not reciprocal wavelength without the 2*pi factor.
- 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.
Alternative or Complementary methods
Use the complete unit and origin definitions, and distinguish a coordinate conversion from a density Jacobian or a physical measurement.
