How many PSI is 1 bar? How to convert bar to psi? Bar and psi are both units of pressure. Bars are used in the metric system, and psi (pounds per square inch) are based on the avoirdupois system (that’s just a fancy way of referring to a system that uses pounds and ounces as … Read more
How do I convert kilowatt-hours to amp-hours? In many cases, we need to convert kWh to Ah. With smaller 12V batteries, we also need to convert kWh to mAh. We will look into how does kWh to amp-hours (Ah) conversion. You will also find a kWh to Ah calculator that dynamically calculated kWh from Ah … Read more
Specific heat capacity is basically a measure of how hard it is to heat up different materials. To calculate the specific heat capacity (C) of any substance, you will need a specific heat capacity formula (equation, if you will). Further on, you will also find a specific heat capacity calculator: You just plug in Q … Read more
The quantity of natural gas is usually expressed in cubic meters (m3). If you want to know much electricity will burning gas generate, you have to convert gas m3 into kWh (kilowatt-hours). You will usually find the m3 on gas meters that look like this: To help you out, we have created an m3 to … Read more
It’s quite easy to convert kW to amps and amps to kW in a simple 1-phase AC circuit (compared to a 3-phase power calculation). That requires only the basic Ohm’s law; you can simply use our kW to amps calculator here for conversion. In a 3-phase AC circuit (usually a 3-phase motor), converting amps to … Read more
kVA to kW is one of the basic conversions in electric engineering. If you want to analyze different electric appliances on an AC circuit, you need to convert kVA to kW. We created an easy kVA to kW calculator that converts kVA into kW with a known power factor. You will also find a kVA … Read more
How to calculate kWh from Ah? In many cases (batteries, for example), we need to convert amp-hours (Ah) to kilowatt-hours (kWh). This is useful for car batteries, for example. With smaller 2500 mAh AA and 1000 mAh AAA batteries, we need to convert mAh to kWh (we’ll show you how to do that as well). … Read more
What is cheaper: gas or electric? The age-old question. Pretty much every big household appliance you can think of – air conditioner, furnace, land mower, tankless water heater, fireplace, and so on – can run on either electricity or gas. The question ‘is gas or electric’ cheaper makes a lot of sense, and knowing the … Read more
The 20-amp circuit is the most common circuit in the US. Since a lot of our visitors have asked ‘how many outlets can you put on a 20-amp circuit’, we decided to give you some insight on this topic. We will not only look at the number of plugs on a 20-amp breaker but, more … Read more
In our article discussing Ah (ampere-hours) and Wh (watt-hours), we got a ton of questions about the longevity of batteries. The question “How long does a battery last?” was a predominant one. To help everybody trying to calculate how long will a battery last, we have created a Battery Life Calculator. It’s quite useful knowing … Read more
