About GTP API Gravity Calculator v2

The GTP API Gravity Calculator v2 (Developed 2025) from Gammon Technical Products, Inc. provides users the ability to determine corrected API at 60 Deg F for jet, gasoline, and diesel fuels. The calculator is a digital version of our GTP-3012-1A and GTP-2727EF slide calculators and it also is capable of calculating the total weight of the fuel

What GTP API Gravity Calculator v2 Is Used For

GTP API Gravity Calculator v2 appears to be a reference-style utility for fuel measurement and correction tasks. Based on the metadata, it is designed to help users determine corrected API gravity at 60°F for jet fuel, gasoline, and diesel, and it also includes a calculation for total fuel weight. This suggests it is most useful in technical, operational, or field settings where quick fuel property calculations are needed on a phone.

The app is described as a digital version of Gammon Technical Products’ slide calculators, so it may be intended for users who already work with API gravity values and fuel handling procedures. The listed permissions, including network access and storage access, suggest it may need connectivity or local file access for app functions, but the metadata does not explain exactly how those permissions are used. As a phone app in the Books & Reference category, it seems oriented toward quick lookup or calculation rather than broad device control.

Common uses

Estimate fuel weight from entered fuel values
Support fuel-related work with jet, gasoline, and diesel
Use as a phone-based reference tool in the field

Fit technical, industrial, or training workflows

Best for:
