Put three or four ice cubes inside a glass of water. Place the glass in the room you want to measure and leave the room. After four minutes have passed, check to see if there is condensation on the outside of the glass. If there is, the humidity is high. If there’s no condensation, then your humidity is on the lower side.

The next unit of humidity measurement is mixing ratio. The mixing ratio is defined as the mass of water vapor divided by the mass of dry air it is contained in. Units are therefore mass/mass, therefore dimensionless. The mixing ratio is defined as: MR = 621.9907 ew/ (P – ew) Where. ew = partial pressure of water vapor.To calculate relative humidity with temperature and dew point, follow the given instructions: Measure the air temperature T, in °C.
