Units of Measure
The following factors given below are intended for orientation and the conversion of the SI units
to common units of measure for the American market.
bar
Unit of measure for pressure p [bar]
All pressure [bar] specifications stand for overpressure [bar o] = positive pressure [bar g],
unless expressly described otherwise (e.g. absolute pressure [bar a]).
Conversion:
1 bar = 14.50376… psi [pound-force per square inch]
°C
Unit of measure for temperature T [degrees Celsius]
Conversion from Celsius to Fahrenheit: °C
1.8 + 32 = °F [degrees Fahrenheit]
h
Unit of measure for time t [hour]
K
Unit of measurement for temperature T and temperature differences ΔT [Kelvin]
Conversion:
273.15 K = 0 °C
kg
Unit of measure for mass m [kilogram]
Conversion:
1 kg = 2.20462 … lb [Latin: libra; pound]
l/min
Unit of measure for volume flow rate V [liters per minute]
Conversion:
1 l/min = 0.06 m
3
/h [cubic meters per hour]
1 l/min = 0.26417… gpm (US) [gallons per minute (US)]
1 m
3
/h = 4.40286… gpm (US) [gallons per minute (US)]
lx
Unit of measure for luminance intensity E
v
[lux]
m
Unit of measure for length l [meter]
Conversion:
1 m = 3.28083… ft [feet]
mm
Unit of measure for length l [millimeter]
Conversion:
1 mm = 1/25.40005 in [inch] = 0.03937 in [inch]
Nm
Unit of measure for moment/torque M [newton meter]
Conversion:
1 Nm = 0.737 lbft [pound-force feet]
rpm
Unit of measure for speed n [revolutions per minute]
Conversion:
1 U/min = 1 rpm [revolutions per minute]
µm
Unit of measure for length l [micrometer]
MΩ
Unit of measure for electrical resistance R [Mega Ohm = 1 million ohms]
pS/m
Unit of measure for electrical conductivity of materials κ [picosiemens per meter]
