Frequently Asked Questions About Bar to Kilopascals (kPa)
People often have specific questions about converting pressures from bar to kPa. Here are the answers to some of the most common questions people ask about converting from bar to kilopascals.
What is bar in pressure?
The bar is a metric unit of pressure defined as equal to exactly 100 kilopascals (kPa), 100,000 Pascals (Pa), or 100,000 newtons per meter squared (N/m2). It is roughly equivalent to the atmospheric pressure on Earth at an altitude of 111 meters and a temperature of five degrees Celsius. It is often used in atmospheric pressure measurements, meteorology, oceanography, scuba diving, engineering, the petrochemical industry, tire pressures, fluid pressures, and pressure gauges. Bar comes from the word “báros”, meaning weight in Greek.
What unit is mbar?
The millibar, abbreviated as mbar, is a metric unit of pressure. A mbar is equal to 100 pascals (Pa) or 0.1 kilopascals (kPa). While the official symbol is mbar, you might come across the older abbreviation of ‘mb’.
What does kPa stand for?
The unit of pressure kPa stands for kilopascal. A kilopascal is defined as the pressure exerted by 1,000 newtons per square meter. This makes sense since pressure equals force per unit area, in this case, newtons per square meter.
In SI base units, a kilopascal is equal to 1,000 kilograms per meter per second squared. It is a multiple of the Pascal pressure unit, which is a derived unit of pressure equal to one newton per square meter (N/m2). The Pascal unit of pressure is named after Blaise Pascal, a French mathematician, physicist, and philosopher.
Kilopascals (kPa) are the standard unit of pressure in countries that use the International System of Units (SI units). In academia, kilopascals are used in chemistry, engineering, hydraulics, physics, and geophysics. You will encounter kPa in everyday life when using a pressure measurement device to check tire pressure, water pressure, air pressure, and pressure tanks.
In countries that use the imperial system of measurement or the United States customary system of units, psi is the preferred unit of pressure.
How do you convert bar to kPa?
To convert from bar to kilopascals (kPa) multiply the bar value by a conversion factor of 100, which is the number of bar in one kPa. Be careful when converting to keep track of rounding errors, as this can lead to issues when a high degree of precision is required. We address the details for doing a reverse unit conversion below.
How do you convert kPa to bar?
To convert from kilopascals (kPa) to bar divide kPa by a conversion factor of 100, which is the number of kPa in one bar. Alternatively, you can use a conversion table or conversion chart to convert from kPa to bar. Conversion tables have conversion factors that help you quickly change between pressure units.
How many kPa makes a bar?
There are 100 kilopascals (kPa) in a bar.
Is kPa the abbreviation for kilopascals?
Yes, kPa is the abbreviation for kilopascals, which is one of the types of measurement for pressure. The prefix ‘kilo,’ abbreviated as ‘k’ in ‘kPa’, represents a factor of 103 in exponential notation.
How many bars are in a kilobar?
There are 1000 bars in a kilobar.
How do you convert bar to kilobar?
You have two conversion options to convert bar to kilobar. The first option is to divide bar by 1000, which is the number of bar in one kilobar. The second option is to multiply bar by 0.001. Both approaches will give you the correct kilobar value.
How many kilopascals are in 10 meters of water?
There are 98.0638 kilopascals (kPa) in 10 meters of water.
What is considered high and low barometric pressure?
A normal pressure barometric range is 0.98 bar to 1.05 bar. In terms of kilopascals, the normal barometric pressure range is between 98 kPa and 105 kPa.
Normal sea-level pressure, also called atmospheric pressure, is 1.0132075 bar, which is equal to 101.32075 kPa.
Is 101.3 kPa a standard pressure?
Standard pressure is equal to 101.3 kPa, which is equivalent to 1 standard atmosphere (atm), 760 mmHg, 760 torr (Torr), or 1.013 bar.
How many bars of pressure can a human survive?
Humans can generally function at pressures up to 2.5 bar for limited periods of time, which is 2.5 times the atmospheric pressure. At pressures above this, a person, such as a scuba diver, would need to substitute oxygen for other gases to avoid oxygen toxicity.
What are the different units of pressure?
The names and abbreviations for commonly used units of pressure include:
- Megapascals (MPa)
- kilopascals (kPa)
- Pascals (Pa)
- standard atmospheres (atm)
- torr (Torr)
- pounds per square inch (psi)
- pounds per square foot (psf)
- millibar (mbar)
- millimeters of mercury (mmHg), historically measured using a column of mercury.
- inches of mercury (inHg)
- dyne (dyn)

- kilopond per square centimeter (kp/cm2)
- kilogram-force per square millimeter (kgf/mm2)
- kilonewton per square meter (kN/m2)
- newton per square meter (N/m2)
What is the metric unit of distance?
The metric distance unit is the meter. Every metric distance unit refers to the meter, such as the centimeter or kilometer.
What is the metric unit of mass?
The most commonly encountered metric mass unit is the gram. Other metric units of mass refer to the gram, such as the kilogram or microgram.
