• #### Film Developer Ratio Calculator

This is a calculator that is used to convert a ratio mixture to a final volume in milliliters. As an example, a film developer or other chemical calls for a 1:4 ratio. Which means one part chemical ...

• #### Gas flow conversion (m3/h to Nm3/h)

Converts a volume flow at operating conditions to a flow rate at defined normal conditions and vice versa.

• #### Harmonic Frequency

Computes the tension or frequency of a taut wire.

• #### Harmonic Wavelength

Computes the harmonic wavelength for various lengths of taut wire.

• #### Heat Index

The Heat Index, also known as the apparent temperature, measures how hot it feels in the shade (or at night) with a light breeze (6 mph). Exposure to full sun can add up to 15F to the Heat Index value ...

• #### Humiture Index

Calculates humiture, which is an index that relates both air temperature and relative humidity to provide an indication of how hot it feels to a person.

• #### Ideal Gas Law

Calculates values for the Ideal Gas Law. Avogadro's law states that equal volumes of different gases at the same temperature and pressure contain equal numbers of molecules.
