Translation formulas

1.

Temperature

degrees Celsius (ºC)

°C = (°F – 32) × 0,55

degrees Fahrenheit (ºF)

°F = °C × 1,8 + 32

Kelvin (K)

K = °C + 273,15

2.

Atmosphere pressure

hectopascal (hPa)

1 hPa = 1 mb = 0,7506 mm Hg

millibar (mb)

1 mb = 1 hPa = 0,7506 mm Hg

millimeters of mercury

(mm Hg)

1 mm Hg = 1,3332 hPa = 1,3332 mb

760 mm Hg = 1013,3 hPa = 1013,3 mb

3.

Wind speed

meter per second (m/s)

1 m/s = 3,6 km/h

kilometer per hour (km/h)

1 km/h = 0,278 m/s

4.

Amount of precipitation

millimeter (mm)

1 mm = 1 l/m²

liter per square meter (l/m²)

5.

Solar radiation

mega joule per square meter (MJ/m²)

1 MJ/m² = 0,277 kW/h

kWh per hour (kW/h)

1 kW/h = 3,6 MJ/m²

6.

Radioactivity

Becquerel (Bq)

1 Bq = 1 dez./s *

7.

Dose of absorbed radiation

micro roentgen per hour (µR/h)

1 µR/h = 0,01 µSv/h

Sievert per hour (Sv/h)

1 µSv/h = 100 µR/h
