Sizing heat exchangers and piping using legacy or international unit data.
Tips & Best Practices
-
Verify unit definitions when working with historical or cross-regional data.
-
Use the conversion for consistency between different calorie definitions in thermal conductivity.
-
Consider the small difference between units insignificant for general applications but critical for precise scientific work.
-
Apply conversions before performing energy-loss or heat transfer calculations.
Limitations
-
The difference between the two units is minimal, around 0.07%, which may be negligible in many engineering cases.
-
Precision is essential in scientific research or when comparing data from different standards.
-
Not intended for units outside of the specified kilocalorie (IT) and kilocalorie (th) per hour per meter per °C.
Frequently Asked Questions
