What does 1 calorie (th)/second represent?

It is a power unit equal to one thermochemical calorie of energy transferred per second, defined as exactly 4.184 watts.

Why convert calorie (th)/second to Btu (IT)/hour?

Converting allows interpreting thermal power data in Btu per hour, which is widely used in HVAC and heating system design standards.

Can this converter be used for all types of calories or Btus?

No. This converter uses the thermochemical calorie and the International Table Btu; other definitions will yield different results.

What Is This Tool?

This converter transforms power values from calorie (th)/second, a unit representing thermochemical calorie energy per second, into Btu (IT)/hour, the International Table British thermal unit per hour. It is useful for heat transfer calculations in HVAC, laboratory calorimetry, and heating equipment.

How to Use This Tool?

Enter the power value in calories (th) per second in the input field
Select the source unit as calorie (th)/second and the target unit as Btu (IT)/hour
Click the convert button to get the equivalent power in Btu (IT)/hour
Use the results for HVAC design, thermal calculations, or energy analysis

Key Features

Converts power units between calorie (th)/second and Btu (IT)/hour accurately
Supports energy transfer measurements relevant to heating and cooling systems
Easy-to-use interface for quick conversions
Helps translate legacy thermal power data into commonly used heating units

Examples

2 calorie (th)/second converts to 28.552801186 Btu (IT)/hour
0.5 calorie (th)/second equals 7.1382002965 Btu (IT)/hour

Common Use Cases

Reporting heat flow in laboratory calorimetry experiments
Specifying heating element or burner power using legacy units
Designing HVAC equipment and rating furnace or air-conditioner capacity
Estimating building heat loss or gain and sizing heat exchangers

Tips & Best Practices

Confirm you are using the thermochemical calorie definition for accuracy
Use the converter to interpret old thermal power data in modern units
Validate results when converting to prevent errors from unit misunderstandings
Apply conversion rates consistently when modeling heat transfer systems

Limitations

Calorie (th)/second is less common in modern engineering, which may cause confusion
Conversion precision depends on using the exact thermochemical calorie value of 4.184 joules
Btu (IT)/hour refers specifically to the International Table British thermal unit; other Btu variants differ
Possible conversion errors if unit definitions are not clearly understood
