Metric Conversions
1 Psi = 6.895 kPa (Kilo Pascals) at 65°F Air = 18.3°C Air
Sq. Ft. EDR at 1 Psi (6.895 kPa) at 65°F Air (18.3°C) Air x 240 BTU = Total BTU’s (Watts)
1 BTU/HR. = 0.2931 Watts
1 Foot = 0.3048 Meters - 1 Meter = 3.2808 Feet
1 BTU/HR/FT = 0.9616 Watts/Meter
10.7639 Sq. Feet = 1 Square Meter
1 Lbs = 0.4536 Kg (Kilograms)
1 Inch = 25.4 mm (Millimeters)
Note:
All shown capacities based on finned length at a water velocity of three feet per second or 0.9144 meter per second or greater.
