![]() Multiply by the conversion value in the right column in the table below.ĥ bar * 100000 = 500000 Pa To simply convert from any unit into pascals, for example, from 5 bar, just Where S is our starting value, C is our conversion factor, and How to Convert Units of PressureĬonversions are performed by using a conversion factor. By knowing the conversion factor, converting between units can become a simple multiplication problem: Some are obvious, such as pounds per square inch, but even the SI standard Pascal is actually an expression of one Newton per square meter. Since pressure is derived from force and area, many units for pressure directly relate force to area. Where P is equal to pressure, F is the normal force and A is area. wind_speed: Wind speed in ft/s, km/h, kn, m/s, or mphĮxample of various device class icons for sensors.Pressure is a scalar quality reflecting how force acts on a surface.weight: Generic mass in kg, g, mg, µg, oz, lb, or st.water: Water consumption in L, gal, m³, ft³, or CCF.volume_storage: Generic stored volume in L, mL, gal, fl. ![]() volume: Generic volume in L, mL, gal, fl.volatile_organic_compounds_parts: Ratio of volatile organic compounds in ppm or ppb.volatile_organic_compounds: Concentration of volatile organic compounds in µg/m³.timestamp: Datetime object or timestamp string (ISO 8601).sulphur_dioxide: Concentration of sulphur dioxide in µg/m³.speed: Generic speed in ft/s, in/d, in/h, km/h, kn, m/s, mph or mm/d.sound_pressure: Sound pressure in dB or dBA.signal_strength: Signal strength in dB or dBm.pressure: Pressure in Pa, kPa, hPa, bar, cbar, mbar, mmHg, inHg or psi.precipitation_intensity: Precipitation intensity in in/d, in/h, mm/d or mm/h.precipitation: Accumulated precipitation in cm, in or mm.power_factor: Power factor (unitless), unit may be None or %.pm10: Concentration of particulate matter less than 10 micrometers in µg/m³.pm25: Concentration of particulate matter less than 2.5 micrometers in µg/m³.pm1: Concentration of particulate matter less than 1 micrometer in µg/m³.nitrous_oxide: Concentration of Nitrous Oxide in µg/m³.nitrogen_monoxide: Concentration of Nitrogen Monoxide in µg/m³.nitrogen_dioxide: Concentration of Nitrogen Dioxide in µg/m³.monetary: The monetary value ( ISO 4217).moisture: Percentage of water in a substance in %.irradiance: Irradiance in W/m² or BTU/(h⋅ft²).illuminance: The current light level in lx.humidity: Percentage of humidity in the air in %.frequency: Frequency in Hz, kHz, MHz, or GHz.enum: Has a limited set of (non-numeric) states.energy_storage: Stored energy in Wh, kWh, MWh, MJ, or GJ.energy: Energy in Wh, kWh, MWh, MJ, or GJ.distance: Generic distance in km, m, cm, mm, mi, yd, or in.data_size: Data size in bit, kbit, Mbit, Gbit, B, kB, MB, GB, TB, PB, EB, ZB, YB, KiB, MiB, GiB, TiB, PiB, EiB, ZiB or YiB. ![]()
