What does kilocalorie (th)/hour measure?

It measures power as the rate of heat transfer equal to one thermochemical kilocalorie per hour.

When should I convert from kilocalorie (th)/hour to microjoule/second?

When translating legacy heat flow data into fine-scale electronic power units used in microelectronics or photonics.

Is this conversion suitable for ultra-low power devices?

While microjoule/second is ideal for ultra-low power, kilocalorie (th)/hour is a large unit and conversions may produce large numbers.

Measuring optical power in photonics and microscopy setups
Describing power from small energy-harvesting devices like tiny solar cells

Tips & Best Practices

Verify use of the thermochemical kilocalorie definition for consistent conversions
Cross-check unit application for compatibility especially in thermal vs electronic contexts
Use careful numerical handling when converting large values due to differences in unit scale

Limitations

Kilocalorie (th)/hour is large compared to microjoule/second, which may lead to very large converted numbers
Conversion accuracy relies on consistent unit definitions and correct timing conversions
Not suitable for measurements that require direct use of microjoule/second without intermediate conversion
