FluffyBench

Pressure Converter

Convert pascals, kilopascals, bar, standard atmospheres and psi. 1 atm is exactly 101,325 Pa, 1 bar is 100,000 Pa, and 1 psi is about 6,894.76 Pa.

Need a pressure in a different unit?

Tire gauge in psi, manual in kPa? FluffyBench's Pressure Converter gives you the same pressure in the unit you need, as you type. Copy the number, then keep the reading's gauge or absolute label beside it.

What changes when you convert pressure?

Pressure is a push spread over an area. Converting it is like giving a distance in miles or kilometers: the number and the label change, but the push stays the same. Here's one standard atmosphere written in each of the five units FluffyBench offers.

A list labeled 1 standard atmosphere: 101,325 Pa; 101.325 kPa; 1.01325 bar; 1 atm; ≈ 14.6959 psi, bracketed together as five labels for one pressure.
Smaller units need bigger numbers. The ≈ marks the one rounded value. How we measured

Converting pressure in FluffyBench's Pressure Converter

Here's a tire reading of 32 psi converted to kilopascals, from choosing the units to copying the answer.

  1. FluffyBench's Pressure Converter opens with From Kilopascal and To Pound-force per square inch, with the swap arrows beside From.
    FluffyBench's Pressure Converter opens with From Kilopascal and To Pound-force per square inch, with the swap arrows beside From.
    Step 1. From is the unit you have; To is the unit you need. FluffyBench opens on kilopascals to psi, and a tire gauge reads psi, so swap the two.
    1. Tap the arrows to swap From and To.
  2. After the swap, From is Pound-force per square inch and To is Kilopascal.
    After the swap, From is Pound-force per square inch and To is Kilopascal.
    Step 2. Now psi goes in and kilopascals come out. For bar, atm or pascals, tap From or To and pick from the list.
    1. From now reads psi.
    2. To now reads Kilopascal.
  3. Input value is 32, labeled psi.
    Input value is 32, labeled psi.
    Step 3. Type the number from your gauge, without its unit. The answer updates as you type; there's no Convert button.
    1. Type 32 in Input value.
    2. The input is in psi.
  4. The result reads 220.63223338139 kilopascals, with Copy above it and the same pressure in the other units below.
    The result reads 220.63223338139 kilopascals, with Copy above it and the same pressure in the other units below.
    Step 4. Read the answer in kilopascals: about 220.6 kPa.
    1. Read 220.63223338139 kilopascals.
    2. Copy takes the number, without kPa.
    3. Each other unit has its own Copy button.

If FluffyBench asks for a decimal number, type the number by itself, without a unit or commas. If Copy is unavailable, select the result and copy it yourself.

Does your pressure reading start at the surrounding air or at zero?

A tire gauge counts from the air around it. That's gauge pressure, written psi(g). Absolute pressure counts from zero, so it includes the air too, written psi(a).

A to-scale bar: the air, 14.6959 psi, sits under the 32 psi(g) tire gauge reading. Together they reach 46.6959 psi(a), about 46.7 psi(a), counted from zero.
The same tire: 32 psi(g) on the gauge is about 46.7 psi(a) once the air is counted.

The air in that picture is one standard atmosphere, a fixed unit of 101,325 Pa. Real air pressure shifts with weather and altitude, so treat it as a stand-in, not today's reading.

FluffyBench's Pressure Converter changes only the unit: 32 psi(g) becomes about 220.6 kPa, still gauge. It doesn't add the air or work out which kind of reading you have, so take that label from the gauge, manual or spec sheet.

How do you record a converted pressure?

Copy gives you the number alone, so the unit and the gauge or absolute label are yours to add. A form field already labeled kPa needs just the number; a note or a message needs both labels beside it.

Step 1 shows a real FluffyBench result with Copy. Step 2 shows the copied text, the number with no unit, and notes that a result shown as 101,325 Pa copies without its comma. Step 3 shows an illustrated note reading Front tire: 220.6 kPa (gauge), with kPa (gauge) typed by hand.
The note rounds to 220.6 kPa; the extra digits don't make a tire gauge more precise.
