Conversion Calculators
Unit-of-Measure Converters
Due to the several forms in which industrial gases are used and delivered throughout the world, and the diversity of applications and use rates, the industrial gas industry uses many different units to measure flow rates, usage rates, pressure, temperature, volumes, plant capacity, sizes and weights of equipment, volume of product, electrical motor ratings, etc.
This set of on-line calculators make unit conversions simple.
- Each calculator contains a table which lists commonly encountered units of measure
- Enter the value you need to convert in the box alongside the appropriate unit of measure
- Click anywhere or hit Enter. Equivalent values will appear beside each alternative unit of measure
| Name of Converter | Units Converted |
|---|---|
| Usage Rate / Flow Rate | (SCF, Nm³, gallons, tons, metric tons / per Hour, Day, Month, Year) |

| Argon Quantity | (Gas and Liquid, Volume and Weight – English and Metric units) |
| CO2 Quantity | (Gas and Liquid, Volume and Weight – English and Metric units) |
| Power | (HP – kW) |
| Energy | (BTU – Joule) |
| Weight | (Pound, Kilogram, Short (“English”) ton, Metric ton) |
| Length | (“English” – Metric) |
| Area | (“English” – Metric) |

- Conversion factors used in the calculations are typically accurate to 4 or 5 significant figures.
- Results normally display up to four figures beyond the decimal point.
- If the calculated result is a very small number (<0.0001) additional figures will display.
- Scf (standard cubic foot) gas measured at 1 atmosphere and 70°F.
- Nm³ (normal cubic meter) gas measured at 1 atmosphere and 0°C.
- Liquid measured at 1 atmosphere and boiling temperature.
Note: While the industrial gas industry uses a 70°F reference temperature for SCF, many chemical and refining companies use a 60°F base.
The difference is about 2% in terms of weight. If precise calculations are being done, be sure to check the temperature basis for any “SCF” numbers.
