By allowing fluid flow experts to include U.S. conventional measures into foreign metric systems for engineering, process, and utility uses, this tool enables users to convert Gallons per Minute (GPM) to Liters per Second (L/s).
Definition: Gallons per Minute (GPM)
A U.S. conventional unit measuring the volume of fluid flowing every minute is Gallons per Minute (GPM). Common applications include plumbing, irrigation, HVAC, water treatment, and fire protection.
Key Applications of Gallons per Minute (GPM):
- Flow measurement in irrigation systems and water pumps.
- Specification of commercial and residential plumbing fixtures.
- Evaluation of sprinkler systems and fire suppression.
- Monitoring of water flow in agricultural and industrial applications.
Definition: Liters per Second (L/s)
A metric measurement called liters per second (L/s) measures fluid flow in terms of liters moved per second. Standard in scientific, industrial, and municipal use, it is perfect for high-flow systems.
Key Applications of Liters per Second (L/s):
- Design of municipal infrastructure and water distribution.
- HVAC systems’ chilled and hot water loops.
- Control of chemical flow and industrial processes.
- Design of firefighting and emergency systems.
Formula for GPM to L/s Conversion
Gallons per Minute (GPM) can be converted to Liters per Second (L/s) by applying the formula:
Flow (L/s) = Flow (GPM) × 0.0630902
Explanation: One U.S. gallon per minute is approximately equal to 0.0630902 liters per second.
Example Calculation
If your pump delivers 100 GPM, convert it to L/s:
100 × 0.0630902 = 6.30902 L/s
So, a flow of 100 Gallons per Minute is equivalent to 6.30902 Liters per Second.
Quick Reference Conversion Table
Gallons per Minute (GPM) | Liters per Second (L/s) |
1 GPM | 0.0630902 L/s |
10 GPM | 0.630902 L/s |
50 GPM | 3.15451 L/s |
100 GPM | 6.30902 L/s |
250 GPM | 15.77255 L/s |
500 GPM | 31.5451 L/s |
1,000 GPM | 63.0902 L/s |
Uses of GPM to L/s Conversion
- Include U.S. flow data into universally accepted engineering designs.
- Help with international project paperwork and system audits.
- Enhance specification clarity for international equipment sourcing.
- Guarantee compatibility with sensors and metric-based instruments.
- Assist fluid systems’ performance testing, simulation, and modeling.
For experts in water management, industrial automation, and fire safety engineering who must confidently convert U.S. flow measurements into SI-compliant values, this conversion tool is essential.
