GasUnits by Gulfstream LNG is the industry’s most versatile universal gas‑unit converter — purpose‑built for professionals who work with natural gas and LNG. Our sector deals in billions, trillions, and even giga‑ and peta‑scale units, where a single miscalculation can derail a deal, distort a forecast, or undermine a technical analysis. GasUnits removes that risk. Created by Vivek Chandra, a seasoned LNG and gas entrepreneur, GasUnits is a free public‑service app designed to simplify the complex. It converts 90+ gas volume, rate, and price units with precision, delivering exact results where possible and smart, composition‑based estimates where required. Choose from three standard gas heating values (1000, 1036, or 952 Btu/ft³), switch between gas volume, gas rate, and gas price calculators, and even compute barrels of oil equivalent using either 6,000 ft³ or 5,800 ft³ per boe. Every result is cleanly formatted and can be copied instantly into your reports, emails, or models. Designed to be fast, easy to use, intuitive, and error‑proof, GasUnits helps traders, engineers, analysts, and commercial teams move with confidence — whether you’re validating a calculation, checking a contract number, confirming a conversion on the go, or aligning stakeholders around a single defensible figure. GasUnits by Gulfstream LNG — simplifying the world’s most complex gas conversions, one calculation at a time. A public service by Gulfstream LNG is an independent LNG export project under development in Louisiana, USA. Disclaimer: Conversions use industry-standard factors.
