GET Request String Parser
The GET Request String Parser is a handy tool for breaking down HTTP GET request strings into parameter-value pairs and decoding URL-encoded sequences if necessary. By using this parser, you can easily extract and analyze the individual components of a GET request.
Saturation vapor pressure
This online calculator computes saturation vapor pressure for a given temperature and atmospheric (barometric) pressure
Relative humidity to absolute humidity and vice versa calculators
The first calculator converts relative humidity to absolute humidity for a given temperature and barometric pressure. The second calculator does the opposite - converts absolute humidity to relative humidity for a given temperature and barometric pressure. Some theory and formulas can be found below the calculator.
Humidification Load Calculator - Find the Perfect Humidifier
