How this luminous intensity converter works

Candela (cd) is used as the internal base unit. Every value you enter is first converted to Candela using exact SI factors, then translated to the requested unit with the same data pulled from the SI Brochure and NIST SP 811.

Key luminous intensity relationships

  • 1 Candlepower = 1 Candela
  • 1 Hefnerkerze = 0.92 Candela

Where luminous intensity units are used

Lighting designers, display manufacturers, and imaging scientists track these optical quantities when tuning sensors, screens, and illumination systems. The luminous intensity converter covers real-world units such as Candela and Candlepower, giving teams a trusted reference when cross-checking data between labs, suppliers, and regulatory filings.

Tips for accurate luminous intensity conversions

  • Always verify the unit symbol in your worksheet—this converter normalizes values through Candela, which is the SI reference for luminous intensity measurements.
  • When jumping between Candela and Candlepower, watch metric prefixes and rounding. A misplaced milli-, micro-, or kilo- prefix can produce errors of several orders of magnitude.
  • Document the context (test conditions, instrument resolution, uncertainty) whenever you publish luminous intensity conversions so coworkers and auditors can reproduce your results.
