Conversion Factor: Teaspoon Per Second → Litre Per Second
1
Understanding the Measure: Volume Flow Rate
Volume flow rate tells us how much space a fluid occupies as it moves each second. It is expressed as a volume unit divided by time, such as litres per second (L/s) or teaspoons per second (tsp/s). Both units belong to the same measure, so they can be directly compared using a single conversion factor.
Defining the Units
Teaspoon Per Second (tsp/s)
A teaspoon is a culinary volume unit. In the United States, 1 tsp = 4.92892159375 mL, which equals 0.00492892159375 L. When we say “tsp/s,” we are describing how many teaspoons of liquid pass a point each second.
Litre Per Second (L/s)
The litre is the standard metric unit for volume. One litre equals 1,000 mL. “L/s” is the most common way to express industrial, scientific, or everyday flow rates.
How to Convert
The conversion is a simple multiplication:
Flow (L/s) = Flow (tsp/s) × 0.00492892159375
Because the factor is constant, you can apply it to any value of tsp/s.
Worked Example
Problem: Convert 25 tsp/s to litres per second.
- Write the formula: L/s = tsp/s × 0.00492892159375.
- Insert the value: L/s = 25 × 0.00492892159375.
- Calculate: 0.12322303984375 L/s.
- Round to four significant figures (as we do for all results): 0.1232 L/s.
So, 25 tsp/s ≈ 0.1232 L/s.
Practical Applications
- Cooking & Baking: Small‑scale recipes often call for a steady drip of liquid, such as a sauce or glaze. Measuring the flow in tsp/s helps maintain consistency.
- Laboratory Pipetting: Precision dispensers may be calibrated in teaspoons per second for low‑volume reagents.
- Home Brewing: When adding hops or flavor extracts, a brewer might monitor the rate in tsp/s to avoid over‑concentration.
- Medical Infusion: Though modern devices use mL/h, older manual drips were sometimes described in tsp/s for pediatric dosing.
Why Use the Metric Equivalent?
Switching to L/s lets you compare small‑scale flows with larger systems, such as water‑treatment plants or HVAC units. It also removes ambiguity when sharing data across borders, because the litre is universally understood.
Teaspoon Per Second to Litre Per Second Conversion Table
Each row applies the same rule: multiply teaspoons per second by 0.00492892159375 and round to four significant figures.

|---|---|
| 1 tsp/s | 0.004929 L/s |
| 2 tsp/s | 0.009858 L/s |
| 5 tsp/s | 0.02464 L/s |
| 10 tsp/s | 0.04929 L/s |
| 20 tsp/s | 0.09858 L/s |
| 50 tsp/s | 0.2464 L/s |
| 100 tsp/s | 0.4929 L/s |
| 500 tsp/s | 2.464 L/s |
Key Takeaways
Converting between teaspoons per second and litres per second is a matter of multiplying by 0.00492892159375. The result lets you bridge culinary precision with scientific rigor. Keep the factor handy, and you’ll never be stuck guessing how a small flow compares to a metric standard.
