How this temperature interval converter works

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

Key temperature interval relationships

  • 1 Millikelvin = 0.001 Kelvin
  • 1 Celsius Degree = 1 Kelvin
  • 1 Fahrenheit Degree = 0.555556 Kelvin
  • 1 Rankine Degree = 0.555556 Kelvin
  • 1 Réaumur Degree = 1.25 Kelvin

Where temperature interval units are used

Thermal engineers, HVAC professionals, and chemists rely on accurate heat and thermodynamics conversions to balance energy budgets and ensure safe operating conditions. The temperature interval converter covers real-world units such as Kelvin and Millikelvin, giving teams a trusted reference when cross-checking data between labs, suppliers, and regulatory filings.

Tips for accurate temperature interval conversions

  • Always verify the unit symbol in your worksheet—this converter normalizes values through Kelvin, which is the SI reference for temperature interval measurements.
  • When jumping between Kelvin and Millikelvin, 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 temperature interval conversions so coworkers and auditors can reproduce your results.
