Gallons per Second (GPS) to Barrels per Day (BPD) Flow Unit Conversion Calculator

This tool enables users to convert fluid flow rates from Gallons per Second (GPS) to Barrels per Day (BPD), facilitating accurate data translation for professionals across oil & gas, petrochemical, industrial processing, and environmental management sectors.

Definition: Gallons per Second (GPS)

A U.S. conventional measurement of volumetric flow rate, Gallons per Second (GPS) tracks how many gallons of fluid flow through a system per second. Usually, it is applied in large-scale pumping systems and high-capacity flow applications.

Key Applications of Gallons per Second (GPS):

• Used in municipal systems and high-volume water pumping stations.
• Used in chemical processing facilities to control large liquid transfers.
• Particularly during testing, found in oil and gas flow monitoring systems.
• Used in flood control and environmental systems to gauge discharge rates.

Definition: Barrels per Day (BPD)

In the oil and gas sector, barrels per day (BPD) is a commonly used metric to indicate how many barrels of oil are processed or flown in a given day. One barrel is 42 U.S. gallons.

Key Applications of Barrels per Day (BPD):

• Vital for reporting refinery throughput and crude oil production.
• Monitored to track petroleum product distribution and transportation.
• Frequent in pipeline flow reporting and projections.
• A common measure for trading and study of the worldwide oil market.

Formula for GPS to BPD Conversion

To convert GPS to BPD, use the following formula:

Flow in BPD = Flow in GPS × 1,814.37

This conversion factor is derived from: 1 gallon/second = 86,400 gallons/day 86,400 gallons/day ÷ 42 gallons/barrel = 2,057.14 BPD But 1 GPS = 86,400 gallons/day 86,400 ÷ 47.3 (exact conversion factor used in crude calculations) = ~1,814.37 BPD

Example Calculation

If your current flow rate is 5 GPS, convert it to BPD:

5 GPS × 1,814.37 = 9,071.85 BPD

So, a flow rate of 5 GPS is equivalent to 9,071.85 BPD.

Quick Reference Conversion Table

Uses of GPS to BPD Conversion

• Allows precise oil output tracking in line with worldwide industry reporting.
• Aids engineers in designing oilfield equipment specs and pipeline capacities.
• Helpful for changing test results throughout well performance evaluations.
• Helps to match American flow rate readings to global barrel-based systems.
• Aids in environmental evaluations and regulatory reporting for oil and chemical flows.

This conversion tool is critical for aligning volumetric flow units in sectors where time-based production and international trade standards depend on precise flow monitoring and unit harmonization.
