Sizing a heat pump seems like a daunting task. How do I calculate what size heat pump do I need? How many BTU heat pump do I need? This is usually an estimate that you need an HVAC expert for. We are going to simplify how to calculate what size heat pump do you need. … Read more
“How many watts is [INSERT NUMBER] BTU?” This is a very common question. When you know how many BTU you have, you’re interested in how many watts is that. For that, you will need a BTU to watt converter. How to convert BTU to watts? You only need to know one thing: 1 BTU is … Read more
Watts are a basic unit of power. BTU (British Thermal Unit) is a unit of heat. We need to convert watts to BTU when it comes to different HVAC devices (including air conditioners, furnaces, and so forth). Watt is a SI unit of power equivalent to J/s (joule per second). BTU or British Thermal Unit … Read more
Degrees of Celsius and degrees of Fahrenheit are both units for measuring temperature. To properly read HVAC specification sheets (for air conditioners, furnaces, etc.), you sometimes have to convert Celsius to Fahrenheit (ยฐC to ยฐF). Applies to general weather, body temperature, cooking recipes, and a number of other applications as well. Celsius is usually used … Read more
In the Energy Star certification program for room air conditioners, there is Section 3: Core Qualification Criteria that states: “CEER shall be greater than or equal to the Minimum CEER (CEERmin) as calculated per Equation 2.” If you open a window AC unit’s specification sheet, you will likely see the CEER rating between 8-15. Here … Read more
Airflow is either measured in meter cube per hour (m3/h)ย or CFM. CFM or cubic feet per minute is usually the more useful metric. However, specification sheets of some devices like air purifiers may include m3/h but not CFM. That’s why it’s useful to convert m3/h to CFM. To help you out, we have created an … Read more
To calculate watts-hours from amp-hours, we need to use the following formula: Watt-hours = Amp-hours ร Volts As we can see, amp-hours multiplied by voltage equals watt-hours. Using this equation, we can accurately convert watt-hours from amp-hours. Below the calculator, you can also check an Ah to Wh conversion chart for 120V and 220V circuits, … Read more
Watt-hours and amp-hours are both units for electric charge. 1 watt-hour is defined as 1 watt of power expended for 1 hour. 1 amp-hour is defined as 1 amp of current expended for 1 hour. How do you convert watt-hours to amp-hours? It is possible to convert watt-hours to amp-hours using the following formula: Watt-hours … Read more
If we know the amperage (A), we can easily convert watts to volts. For the W to V conversion, we can use the formula for electric power: P (W) = I (A) * V (V) To calculate volts from watts, we need to rearrange this formula by expressing voltage like this: Volt = Watts / … Read more
Amperes (A), volts (V), and watts (W) are the 3 basic electrical units, connecting electrical current, voltage, and power. Every electric device – from air conditioners to washing machines and generators – includes them in their specification sheets. One of the most common questions here is this: How to convert amps to watts? To convert … Read more
