What is a thermochemical calorie (cal (th))?

It is a historical energy unit defined exactly as 4.184 joules, used primarily in older thermochemical data and heat measurements.

Why convert calorie (th) to megawatt-hour?

To translate older energy data based on heat measurements into modern large-scale electrical energy units for comparison and analysis.

Is this conversion tool suitable for everyday energy billing?

No, because the thermochemical calorie is historical and conversions produce extremely small numbers not practical for typical billing or reporting.

Uses an exact fixed relationship between these energy units
Supports analysis of historical thermochemical data in modern energy contexts
Browser-based tool for quick and easy energy unit conversions
Provides examples for better understanding of conversion outcomes

Examples

1,000,000 cal (th) converts to approximately 0.001162222 MW*h
500,000 cal (th) converts to approximately 0.000581111 MW*h

Common Use Cases

Translating older thermochemical energy values to modern electrical energy units
Analyzing historical heat release or absorption data in newer units
Reporting large-scale electricity production or consumption for utilities
Comparing past thermochemical measurements with current grid energy metrics
Specifying capacities for large energy storage systems in megawatt-hours

Tips & Best Practices

Ensure input values use the thermochemical calorie definition for accurate results
Use this conversion mainly for bridging historical data with current energy metrics
Avoid applying the tool for very small energy values where megawatt-hour units become impractically minute
Double-check converted data when used in critical energy reporting or research
Leverage provided examples to validate conversion outcomes before extensive use

Limitations

The calorie (th) is a historical energy unit less commonly used in modern practice
Conversions from cal (th) to MW*h result in very small values for small inputs
This tool does not address precision issues inherent to outdated thermochemical data
Not suitable for routine energy billing or daily energy management where SI joules or kilowatt-hours are standard
