Hectopascals to Kilopascals Converter
A precision engineering utility for converting Hectopascals (hPa) to Kilopascals (kPa). Features significant figure control, scientific notation, and real-time formula explanation for fluid dynamics and HVAC applications.
About
Precise pressure conversion is the backbone of atmospheric science, aviation altimetry, and HVAC system design. Engineers and meteorologists frequently encounter the Hectopascal (hPa), historically known as the millibar, in weather charts and absolute pressure sensors. However, Kilopascals (kPa) remain the standard in structural engineering and fluid dynamics stress analysis.
This tool bridges that gap with scientific rigor. Unlike generic calculators, it handles the nuance of floating-point arithmetic and provides options for significant figures, ensuring that data integrity is maintained for critical safety calculations. Whether sizing a ventilation duct or calibrating a barometer, the accuracy of the conversion factor 110 is paramount.
Formulas
The relationship between Hectopascals and Kilopascals is linear and defined by the metric prefixes hecto- (100) and kilo- (1000).
The primary conversion equation is:
PkPa = PhPa × 0.1
Alternatively expressed using powers of ten:
PkPa = PhPa × 10−1
To reverse the calculation (kPa to hPa):
PhPa = PkPa × 10
