How to Convert Hectopascals to Pascals

Calculators can be used to convert measurements from one unit to another

To convert a hectopascal measurement to a pascal measurement, multiply the pressure by the conversion ratio. One hectopascal is equal to 100 pascals, so use this simple formula to convert:

pascals = hectopascals × 100

The pressure in pascals is equal to the hectopascals multiplied by 100.

For example, here's how to convert 5 hectopascals to pascals using the formula above.
5 hPa = (5 × 100) = 500 Pa

Hectopascals and pascals are both units used to measure pressure. Keep reading to learn more about each unit of measure.


The hectopascal is equal to 100 pascals, which are defined as the pressure of one newton per square meter. The hectopascal is the internationally adopted unit used to measure atmospheric pressure.

The hectopascal is a multiple of the pascal, which is the SI derived unit for pressure. In the metric system, "hecto" is the prefix for 102. Hectopascals can be abbreviated as hPa, for example 1 hectopascal can be written as 1 hPa.


The pascal is defined as the pressure of one newton per square meter.

The pascal is the SI derived unit for pressure in the metric system. Pascals can be abbreviated as Pa, for example 1 pascal can be written as 1 Pa.

Pascals can be expressed using the formula:
1 Pa = 1 Nm2

Pressure in pascals is equal to the force in newtons divided by the area in square meters.

Unit of Measurement Conversion Made Easy!

There are thousands of units of measure in use across the globe, and converting from one to another can be very difficult since each conversion requires a different formula to derive the result. Our unit of measurement conversion tools are meant to be dead easy. We break the mold of the typical dry and complicated experience. In addition to converting from one measurement to another, we provide the formula so you can see how the conversion is done, use it on you’re own calculator if you need to!

Understanding the Metric System

The metric system makes it relatively easy to convert from one metric unit to another metric unit. The metric system uses a base unit, think meters or grams, and a prefix such as kilo or milli. The prefixes differ from the base units by differing powers of 10. So to convert within the metric system it’s usually a matter of multiplying or dividing by one of the powers of 10.

Here is a list of some of the common metric prefixes:

  • “kilo” – 1,000x larger
  • “hecto” – 100x larger
  • “deca” – 10x larger
  • “deci” – 10x smaller
  • “centi” – 100x smaller
  • “milli” – 1,000x smaller

There is a helpful mnemonic for remembering the prefixes: “King Henry Died Until Drinking Chocolate Milk.”
The u in Until refers to the base unit.
