**Frequently Asked Questions About Kilopascals (kPa) to Standard Atmospheres (atm)**

People often have specific questions about converting from kPa to atm. Here are the answers to some of the most common conversions and questions people ask about kPa to atm.

**What is atm?**

A Standard atmosphere (atm) is a unit of pressure defined as 101.325 kPa, 101,325 Pa, 760 mmHg, 1.01325 bar, 760 torr, 4.6959 psi, or 1 ata (atmosphere absolute). It is equivalent to the average atmospheric pressure on Earth at sea level. It is often used as a standard pressure, also called a reference pressure. For this reason, standard atmospheric pressure is defined as 1 atm of pressure.

**What does kPa stand for?**

The unit of pressure kPa stands for kilopascal. A kilopascal is a pressure of 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 and is equivalent to one newton per square meter (N/m2). Pascals are named in honor of 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). Other countries use pounds per square inch (psi) for pressure measurements. Pounds per square inch is the pressure measurement under the Imperial system of measurement and the United States customary system of units.

In academia, kilopascals are used in chemistry, engineering, hydraulics, physics, and geophysics. In everyday life, you might encounter kilopascals (kPa) while checking car tire pressure, measuring water pressure, taking air pressure, verifying gas pressure, or inspecting pressure tanks.

**What is atmospheric pressure in kilopascals?**

Atmospheric pressure is equal to 101.325 kilopascals (kPa). This pressure is called ‘standard atmospheric pressure’ and equals one standard atmosphere (atm).

**Are kPa or Pa SI units?**

Kilopascals (kPa) and Pascals (Pa) are SI-derived units.

**How do you convert atm to kPa?**

You have two conversion options to convert standard atmospheres (atm) to kilopascals (kPa). The first option is to multiply atm by 101.325, which is the number of kPa in one atm. The atm values cancel, leaving you with kPa.

The second option is to divide the atm value by the conversion factor of 0.00986923266. Both the multiplication and division-based approaches will give you the correct atm value.

Alternatively, you can use a conversion table to convert from atm values to kPa. Conversion tables have conversion factors that help you quickly change between pressure units.

**How do you convert kilopascals (kPa) to pascals (Pa)?**

To convert from kilopascals to pascals, multiply the number of kilopascals by 1,000. The answer will be in terms of Pascals.

**Is kPa bigger than atm? **

Standard atmospheres (atm) are a bigger pressure measurement unit than kilopascals (kPa). There are 101.325 kPa in an atm, but only 0.00986923266 atm in one kPa.

**Is atm the same as kPa?**

No, an atm is not the same as a kPa. One atm equals 101.325 kPa, which means that one standard atmosphere (atm) is 101.325 times larger than one kilopascal (kPa).

**What is 1 atm equal to in kPa and mmHg?**

One standard atmosphere (atm) is equal to 101.325 kilopascals (atm) or 7.50062 millimeters of mercury (mmHg).

**What are the different units of pressure?**

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)
- bar
- 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)

**How do you read a pressure gauge?**

Gauges can report two types of pressure: gauge pressure and absolute pressure. Although gauge pressure is most common, absolute pressure gauges do exist. Gauge pressure is the difference between total pressure (absolute pressure) and atmospheric pressure.

To read a pressure gauge, note the reported pressure. The pressure value will be reported using a needle pointer, digital value, or a rod.

**What is the maximum pressure that a 2 liter soda bottle can hold?**

A two-liter soda bottle made from polyethylene terephthalate (PET) will explode at 10.2 atmospheres (atm). 10.2 atm is equivalent to 1033.515 kPa or 149.8987 psi. Don’t try proving this yourself as no two bottles are alike and high pressures can be dangerous.

**How many significant figures are in 101.325 kPa?**

There are six significant figures (sig figs) in 101.325 kPa, which is the number of kilopascals in one standard atmosphere.

**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.
