Frequently Asked Questions
-
What does erg/hour/square millimeter measure?
-
It measures heat flux density as energy in ergs transferred per hour through one square millimeter, indicating power per unit area in CGS and metric terms.
-
Why convert from erg/hour/mm² to calorie (IT)/minute/cm²?
-
Conversion helps relate legacy CGS-based measurements to more current or application-specific units used in thermal and biomedical fields, enabling better data comparison.
-
Are there any accuracy concerns when converting these units?
-
Yes, differences in unit scales and small conversion factors can cause rounding errors and require careful consideration of measurement conditions.
