Bar to PSI is one of the most common pressure unit conversions. Here, we will help you convert any bars to PSI (Pounds per Square Inch). We will explain exactly how to convert pressure in bars to pressure in PSI with these 2 useful tools: Bar To PSI Calculator. Here, you just insert the number … Read more
When it comes to units of pressure, you will sometimes need to convert kg/cm2 to PSI. Basically, we are converting kilograms per square centimeter to pounds per square inch. We will help you with this pressure unit conversion with a kg/cm2 to PSI calculator, formula (manual calculation), and 0.01-1000 kg/cm2 to PSI conversion chart. Let’s … Read more
When it comes to pressure units, you might need to convert kPa to mmHg. Basically, we are converting kilopascals to millimeters of Hg (mercury). To help you out with this conversion, we created a kPa to mmHg calculator, along with the 1-1000 kPa to Hg conversion chart (below the calculator): Let’s look at one … Read more
If you need to convert ACFM to SCFM, you are in the right place. This is a notoriously difficult conversion; we want to calculate how many Standard Cubic Feet Per Minute (SCFM) we get from certain Actual Cubic Feet Per Minute (ACFM) at certain pressure, temperature, and relative humidity conditions. Basically, in the real world, … Read more
Air compressors, for example, are rated in SCFM (Standard Cubic Feet Per Minute). In many cases, we will have to convert SCFM to ACFM (Actual Cubic Feet Per Minute). The conversion to ACFM (based on actual pressure, temperature, and relative humidity) will give us an idea of what airflow an air compressor can actually produce … Read more
At what pressure (kPa, PSI, mmHg, bar, atm, torr) and temperature (°F, °C, K) does water boil? This is exactly what the water saturation pressure calculators determine. We will show you how exactly to determine the saturation pressure of water at 3 temperature scales (°F, °C, K). Namely, to turn water into vapor at a … Read more
Rankine to Fahrenheit conversion is dead simple. If you want to convert degrees Rankine to degrees Fahrenheit (°R to °F), you only need to subtract 459.67 from degrees Rankine to get degrees Fahrenheit. Obviously, you can use your hand calculator for that. To simplify thing, we have created an online Rankine to Fahrenheit calculator that … Read more
Degrees of Rankine is such a weird temperature unit. Nonetheless, sometimes you will need to convert Fahrenheit to Rankine degrees (°F to °R). Just to simplify all this, we have prepared a Fahrenheit to Rankine conversion calculator. On top of that, we also converted -100°F to 1000°F into Rankine (°R), and summarized all the results … Read more
“I have a 400 sq ft room with 9 ft ceiling height. Sweating at 84°F temperature, I get a lot of sun in South California. I need an air conditioner; what size AC I need? I’m interested in AC BTU for this room size.” This is a question that landed in our inbox. We figured … Read more
EAEER is a less frequently used but the most accurate energy efficiency ratio for air conditioning systems. Despite being seldom specified on the specs sheets, it is the most realistic air conditioner energy efficiency ratio (more than SEER, EER, CEER, IEER). EAEER stands for Energy Adjusted Annual Energy Efficiency Ratio. In contrast to more well-known … Read more
