Calculators

Calculates the air changes per hour (ACH) in a room, which indicates how many times the total air volume in a room is replaced in one hour. This is crucial for ventilation and air quality assessment.

Calculates the boiling point of water at a given altitude, taking into account the decrease in atmospheric pressure with increasing altitude.

Performs addition or subtraction on two matrices of compatible dimensions.

Calculates the work done by a force acting over a distance. Work is calculated using the formula: W = Fd cos θ, where W is work, F is force, d is distance, and θ is the angle between the force and the direction of motion.

Calculates the Brake Specific Fuel Consumption (BSFC) of an engine. BSFC is a crucial metric for engine efficiency, representing the mass of fuel consumed per unit of power generated per hour.

This calculator estimates the impact of cleaning up cigarette butts, showing the volume collected, estimated litter removed, and potential environmental impact.

Calculates adjusted body weight, a weight value used for drug dosing or nutritional calculations in obese patients. This is a more accurate measure than actual body weight in such cases.

Converts power levels between decibels relative to one milliwatt (dBm) and watts. dBm is a logarithmic unit, and this calculator helps convert it to the linear unit of watts.

Calculates the molecular weight (also known as molar mass) of a chemical compound based on the sum of the atomic weights of each element in the molecular formula.

Calculates the frequency of an event or occurrence per unit of time, given the frequency in a different unit of time.
