Key to measurements

All capacities and measurements in the catalog are expressed in uniform values. The conversion chart provides helpful information for their translation into equivalent systems.

Pressure:

1 psi = .069 bar

1 bar = 14.5 psi
= 10 N/cm²

1 MPa = 145 psi

Weight:

1 pound (lb) = .4536 kg

1 kg = 2.205 lbs

1 metric ton = 2205 lbs
= 1000 kg

1 ton (short) = 2000 lbs
= 907.18 kg

Temperature:

To Convert °C to °F:
T °F = (T °C x 1.8) + 32
To Convert °F to °C:
T °C = (T °F – 32) ÷ 1.8

Volume:

1 in³ = 16.387 cm³

1 cm³ = .061 in³
