Kilowatts (kW) to Gigacalories per Hour (Gcal/h) Converter
Convert electrical or thermal power (kW) to Gigacalories per hour. Essential for HVAC engineering, district heating, and boiler energy billing.
About
In the domain of district heating and large-scale industrial thermodynamics, energy is frequently metered in Gigacalories (Gcal) rather than Kilowatts (kW). This creates a disconnect between electrical heating specifications and thermal utility billing. The Kilowatts to Gigacalories per Hour converter bridges this unit disparity, providing high-precision translation for facility managers and HVAC engineers.
Billing for thermal energy often relies on accurate decimal reporting. A rounding error in Gcal/h calculations can lead to significant financial discrepancies over a fiscal year. This tool allows users to control decimal precision, ensuring that the data generated aligns with specific utility provider standards or engineering log requirements.
Formulas
The conversion relates the rate of energy transfer in Joules per second (Watts) to the heat required to raise the temperature of water (Calories).
P(Gcal/h) ≈ P(kW) × 0.0008598452
Conversely, for the inverse calculation:
P(kW) ≈ P(Gcal/h) × 1163
