## What is Gas Pro 2021?

GAS PRO 2021 - Converter tool for Light Hydrocarbon Liquids.

Section - VAC to AIR / AIR to VAC - ASTM Table 56
Density in this section is mass per unit volume at 15°C expressed in kilograms per litre
Correction using factor for converting mass to weight in air and vice versa over density range 0.5000-1.1000 kg/litre.

Section - Weight,MT in US Barrels at 60°F - ASTM Table 58
Density in this section is mass per unit volume at 15°C expressed in kilograms per litre
Converting weight in MT to US Barrels volume.

Section - Density at 60/60°F to Density at 15°C - ASTM Table 21
Density in this section is mass per unit volume at 15°C expressed in kilograms per litre
Conversion will provide density at 15°C of light hydrocarbon liquid from relative density at 60/60°F 

Section - VCF (Volume Correction Factor) - ASTM Table 54
Density in this section is mass per unit volume at 15°C expressed in kilograms per litre
The value must be entered with density at 15°C and temperature measured in degrees Celsius
This gives the factor for converting light hydrocarbon liquid volumes observed at temperature (range from -46°C to +50°C) other than 15°C to the corresponding volumes at 15°C for values fo density in range 0.5000 to 0.653 kg per litre.
