10 hPa is equal to 1000 pascal.
To convert hectopascals (hPa) to pascals (Pa), you multiply the value in hPa by 100. Since 1 hPa equals 100 pascals, converting 10 hPa involves multiplying 10 by 100, resulting in 1000 pascals.

Conversion Formula
The formula to convert hPa to pascal is:
pascal (Pa) = hectopascal (hPa) × 100
This works because 1 hectopascal equals exactly 100 pascals. The hectopascal is a derived unit of pressure, where “hecto-” means 100 times the base unit pascal. So to get pascal from hPa, multiply by 100.
Example: Converting 10 hPa to pascal:
- Start with 10 hPa
- Multiply by 100: 10 × 100 = 1000
- Result: 1000 pascals
Conversion Example
- 5 hPa to pascal:
- Multiply 5 by 100
- 5 × 100 = 500 pascals
- So, 5 hPa equals 500 pascals
- 12.3 hPa to pascal:
- Multiply 12.3 by 100
- 12.3 × 100 = 1230 pascals
- Answer: 1230 pascals
- 0.75 hPa to pascal:
- Multiply 0.75 by 100
- 0.75 × 100 = 75 pascals
- Result is 75 pascals
- -3 hPa to pascal:
- Multiply -3 by 100
- -3 × 100 = -300 pascals
- Negative value means -300 pascals

Conversion Definitions
hPa (hectopascal): A hectopascal is a unit of pressure equal to 100 pascals. It’s used in meteorology and other sciences for measuring atmospheric pressure. The “hecto-” prefix means 100 times the base unit pascal, making it convenient for expressing pressure values in a compact form.
Pascal (Pa): The pascal is the SI unit for pressure, defined as one newton per square meter. It measures force exerted on a surface area and is used widely in physics, engineering, and weather science. It quantifies pressure in terms of force over area precisely and consistently worldwide.
Conversion FAQs
Is the hectopascal bigger or smaller than the pascal?
The hectopascal is bigger than the pascal by a factor of 100. One hectopascal equals 100 pascals because “hecto-” means hundred times the base unit. So 1 hPa represents 100 Pa, making it easier to express larger pressures without using very large numbers.
Can I use the same conversion for negative pressure values?
Yes, the conversion works the same for negative values. If you have -10 hPa, multiply by 100 and get -1000 pascals. Negative pressures might appear in some scientific contexts like vacuum measurements, so the formula applies universally regardless of sign.
Why do meteorologists prefer using hectopascal instead of pascal?
Meteorologists prefer hectopascals because typical atmospheric pressures fall near 1000 hPa, which is easier to read and communicate than 100,000 pascals. The hectopascal simplifies numbers for weather data and forecasts, avoiding cumbersome large figures while retaining precision.
Does converting hPa to Pa affect pressure measurement accuracy?
Converting from hPa to pascal does not affect the accuracy of pressure measurements. The conversion only changes the unit scale by a factor of 100. Provided the original measurement is accurate, the converted value remains precise and reliable for any calculations or analysis.
Are there other pressure units related to hPa and pascal?
Yes, other units include millibar (mb), which equals 1 hPa, kilopascal (kPa), equal to 1000 Pa, and atmospheres (atm), about 101325 Pa. These units are used in different contexts, but converting between them usually involves multiplying or dividing by fixed factors related to the pascal.
