Understanding Cubic Inch Per Second and Litre Per Hour
Both units belong to the volume flow rate family. A cubic inch per second (in³/s) tells you how many cubic inches of fluid pass a point each second. A litre per hour (l/h) tells you how many litres pass the same point in one hour. Converting between them lets engineers, hobbyists, and anyone dealing with fluids speak the same language.
Exact Conversion Factor
The internationally accepted factor is:
1 in³/s = 58.9934304 l/h
Conversion Formula
To move from cubic inches per second to litres per hour, multiply by the factor:
l/h = (in³/s) × 58.9934304
Step‑by‑Step Example
Suppose a small pump delivers 5 in³/s. Apply the formula:
- Multiply 5 by 58.9934304.
- 5 × 58.9934304 = 294.967152.
- Round to a practical precision: ≈ 294.9672 l/h.
The pump moves roughly 295 litres of fluid every hour.
Cubic Inch Per Second to Litre Per Hour Conversion Table
Each row applies the same rule: multiply cubic inches per second by 58.9934304. Values are rounded to four decimal places for easy reading.
| Cubic Inch Per Second (in³/s) | Litre Per Hour (l/h) |
|---|---|
| 1 in³/s | 58.9934 l/h |
| 2 in³/s | 117.9869 l/h |
| 5 in³/s | 294.9672 l/h |
| 10 in³/s | 589.9343 l/h |
| 20 in³/s | 1,179.8686 l/h |
| 50 in³/s | 2,949.6715 l/h |
| 100 in³/s | 5,899.3430 l/h |
| 500 in³/s | 29,496.7152 l/h |
Practical Applications
Knowing how to convert in³/s to l/h is useful in many fields:
- Automotive cooling systems: Engineers often receive flow data in cubic inches but need to size radiators in litres.
- Home brewing: Small pumps are rated in in³/s, while recipes use litres per hour for mash circulation.
- Industrial hydraulics: Legacy equipment may list flow in imperial units, yet modern control software expects metric.
Key Takeaway
One cubic inch per second equals 58.9934304 litres per hour. Use the simple multiplication formula to switch between the two, and refer to the table for quick reference. Ready to convert your own data? Apply the factor and watch your calculations flow smoothly.
