Working in the oil filed, you may need to convert some unit values to another unit valves. I have some conversion unit specially used in the drilling and working over industry. I have 3 parts of the oil field conversion unit. This is the first part which is the conversion of Area, Circulation Rate, Impact Force.

The **RED** number is the conversion unit.

**Area**

Square inches x **6.45** = Square centimeters

Square inches x **645** = Square millimeters

Square centimeters x **0.155** = Square inches

Square millimeters x **0.00155** = Square inches

**Circulation Rate**

Barrels/min x **42** = Gallons/min

Cubic feet/min x **0.000472** = Cubic meters/sec

Cubic feet/min x** 7.48** = Gallons/min

Cubic feel/mm x **28.32** = Liters/min

Cubic meters/sec x **15850** = Gallons/min

Cubic meters/sec x **2118** = Cubic feet/min

Cubic meters/sec x **60000** = Litres/min

Gallons/min x **0.0238** = Barrels/ruin

Gallons/min x **0.134 **= Cubic feet/min

Gallons/min x **3.79 **= Litres/min

Gallons/min x **0.00006309 **= Cubic meters/sec

Litres/min x **0.00001667** = Cubic meters/sec

Litres/min x **0.0353** = Cubic feet/min

Litres/min x **0.264 **= Gallons/min

**Impact Force**

Pounds x **0.0000445** = Dynes

Pounds x **0.454** = Kilograms

Pounds x **4.448** = Newtons

Dynes x**0.00000225** = Pounds

Kilograms x **2.2** = Pounds

Newtons x **0.2248** = Pounds

I hope this conversion unit will be advantageous for you.
