Calculators 101
Temperature Conversion Calculator
A temperature conversion calculator is a tool used to convert a temperature measurement from one scale to another. The most common temperature scales are Celsius (°C), Fahrenheit (°F), and Kelvin (K). A temperature conversion calculator allows users to input a temperature measurement in one scale and then convert it to the desired scale. The calculation is based on the formula for each temperature scale and the conversion factor between the scales. Temperature conversion calculators are commonly used in a variety of fields, including science, engineering, cooking, and medicine, where precise temperature measurements are important.

Humidity Calculator:
A humidity calculator is a tool used to determine the relative humidity of air based on the temperature and moisture content of the air. The relative humidity is a ratio that compares the amount of moisture in the air to the maximum amount of moisture the air can hold at a particular temperature. The relative humidity is expressed as a percentage, with 100% relative humidity indicating that the air is completely saturated with moisture. Calculators for relative humidity can be found online or as a standalone device and are commonly used in various applications such as weather forecasting, indoor air quality control, and HVAC design. The calculation involves inputting the temperature and moisture content of the air, and the calculator then determines the relative humidity based on these inputs.

Relative Humidity Calculator:
A relative humidity calculator is a tool used to determine the relative humidity of air based on the temperature and moisture content of the air. Relative humidity is a ratio that compares the amount of moisture in the air to the maximum amount of moisture the air can hold at a particular temperature. The relative humidity is expressed as a percentage, with 100% relative humidity indicating that the air is completely saturated with moisture. It is commonly used in various applications such as weather forecasting, indoor air quality control, and HVAC design.

BTU Calculator:
A BTU (British Thermal Unit) calculator is a tool used to determine the amount of heat energy required to raise or lower the temperature of a given volume of air or water. BTUs are commonly used as a unit of measurement for heating and cooling systems, and a BTU calculator can help determine the size of the heating or cooling system needed for a given space. The calculation involves determining the volume of the space, the desired temperature change, and the desired temperature range. This information is then used to calculate the BTUs required to heat or cool the space, taking into account factors such as insulation and air flow. BTU calculators are commonly used in HVAC design, home energy efficiency assessments, and other heating and cooling applications.

AirFlow Calculator:
An air flow calculator is a tool used to determine the volume of air moving through a duct system, fan or blower. Air flow is often measured in cubic feet per minute (CFM) or meters per second (m/s). The air flow calculator takes into account factors such as the size of the duct, the velocity of the air, and the density of the air to determine the volume of air moving through the system. This information is important for determining the efficiency of a heating or cooling system and can be used to troubleshoot problems or make improvements to the system. Air flow calculators are commonly used in HVAC design and maintenance, as well as in industrial and manufacturing applications where air flow is a critical factor in process control and efficiency.

Flow Rate: (cfm)
Duct Sizing Calculator:
A duct sizing calculator is a tool used to determine the appropriate size of a duct system used in heating, ventilation, and air conditioning (HVAC) applications. The calculator takes into account factors such as the volume of air to be moved, the desired air velocity, and the available pressure drop to determine the appropriate size of the ducts. Proper duct sizing is important to ensure efficient and effective heating and cooling of space. A duct that is too small can result in insufficient airflow, while a duct that is too large can result in energy waste and higher operating costs. Duct sizing calculators are commonly used by HVAC designers, contractors, and technicians to ensure that duct systems are designed and installed correctly.
