Need to compare water flow in a small garden pump with the volume moving through a large industrial pipe? Converting litres per second to cubic yards per second lets you speak the same language, whether you’re budgeting irrigation or sizing a wastewater treatment system.
Exact Conversion Factor
One litre per second equals 0.001308 yd³/s. The relationship is linear, so you simply multiply the litre‑per‑second value by this factor.
Understanding the Units
Litre per Second (l/s)
The litre is a metric unit of volume equal to one‑thousandth of a cubic metre. When expressed per second, it measures how many litres pass a point each second—a common metric in plumbing, HVAC, and laboratory work.
Cubic Yard per Second (yd³/s)
A cubic yard is an imperial volume unit equal to 0.7645548579 m³. Expressed per second, it is often used in large‑scale civil‑engineering projects, such as storm‑water management or mining operations, where imperial units dominate.
How to Convert
The conversion follows a single multiplication:
yd³/s = l/s × 0.001308
Because the factor is constant, you can apply it to any flow rate without additional steps.
Worked Example
Imagine a pump delivering 25 l/s. Applying the factor:
- Multiply 25 by 0.001308.
- 25 × 0.001308 = 0.0327 yd³/s (rounded to four decimal places).
The pump moves roughly 0.0327 cubic yards of fluid each second, which helps you compare it directly with equipment rated in imperial units.
Litre Per Second to Cubic Yard Per Second Conversion Table
Each row applies the same rule: multiply litres per second by 0.001308 to obtain cubic yards per second. Values are rounded to four decimal places where necessary.
| Litre per Second (l/s) | Cubic Yard per Second (yd³/s) |
|---|---|
| 1 l/s | 0.001308 yd³/s |
| 2 l/s | 0.002616 yd³/s |
| 5 l/s | 0.006540 yd³/s |
| 10 l/s | 0.013080 yd³/s |
| 20 l/s | 0.026160 yd³/s |
| 50 l/s | 0.065400 yd³/s |
| 100 l/s | 0.130800 yd³/s |
| 500 l/s | 0.654000 yd³/s |
Practical Applications
- Irrigation design: Translate a field’s water demand from metric to imperial units to coordinate with equipment suppliers.
- Storm‑water modeling: Convert runoff rates measured in litres per second to cubic yards per second for compliance reports.
- Industrial processes: Align flow‑meter readings with pump specifications that may be listed in different unit systems.
Key Takeaway
Remember the simple rule: yd³/s = l/s × 0.001308. With this factor, you can instantly bridge metric and imperial flow‑rate worlds, making cross‑border projects smoother and calculations faster.
