Cubic inches per second (in³/s) to Litres per hour (l/h) conversion

Conversion between cubic inches per second and liters per hour involves transitioning between imperial and metric volume flow rate units. Understanding the conversion factor and the process ensures accurate results.

Conversion Fundamentals

The conversion relies on the relationship between cubic inches and liters, and seconds and hours

Converting Cubic Inches Per Second to Liters Per Hour

Conversion Factor:

• 1 cubic inch = 0.016387064 liters (exactly)
• 1 hour = 3600 seconds

Step-by-Step Conversion:

1. Cubic inches to Liters: Multiply the volume in cubic inches by the conversion factor to get liters.

   $$\text{Liters} = \text{Cubic Inches} \times 0.016387064$$

2. Seconds to Hours: Since you want liters per hour, multiply by the number of seconds in an hour.

   $$\text{Liters per Hour} = \text{Liters per Second} \times 3600$$

3. Combined Formula: Combining these two steps:

   $$\text{Liters per Hour} = \text{Cubic Inches per Second} \times 0.016387064 \times 3600$$

4. Calculation for 1 Cubic Inch per Second:

   $$\text{Liters per Hour} = 1 \times 0.016387064 \times 3600 = 59.0 \text{ Liters per Hour (approximately)}$$

Therefore, 1 cubic inch per second is approximately equal to 59.0 liters per hour.

Converting Liters Per Hour to Cubic Inches Per Second

Conversion Factor:

• 1 liter = 61.0237 cubic inches
• 1 hour = 3600 seconds

Step-by-Step Conversion:

1. Liters to Cubic Inches:

   $$\text{Cubic Inches} = \text{Liters} \times 61.0237$$

2. Hours to Seconds:

   $$\text{Cubic Inches per Second} = \frac{\text{Cubic Inches per Hour}}{3600}$$

3. Combined Formula:

   $$\text{Cubic Inches per Second} = \frac{\text{Liters per Hour} \times 61.0237}{3600}$$

4. Calculation for 1 Liter per Hour:

   $$\text{Cubic Inches per Second} = \frac{1 \times 61.0237}{3600} = 0.01695 \text{ Cubic Inches per Second (approximately)}$$

Therefore, 1 liter per hour is approximately equal to 0.01695 cubic inches per second.

How to Convert Cubic inches per second to Litres per hour

To convert Cubic inches per second to Litres per hour, multiply the flow rate by the conversion factor between the two units. In this case, $1 \text{ in}^3/\text{s} = 58.993158480372 \text{ l/h}$.

1. Write the conversion factor:
   Use the known relationship between Cubic inches per second and Litres per hour:

   $$1 \text{ in}^3/\text{s} = 58.993158480372 \text{ l/h}$$

2. Set up the conversion:
   Multiply the given value by the conversion factor:

   $$25 \text{ in}^3/\text{s} \times 58.993158480372 \frac{\text{l/h}}{\text{in}^3/\text{s}}$$

3. Cancel the original unit:
   The $\text{in}^3/\text{s}$ units cancel, leaving only Litres per hour:

   $$25 \times 58.993158480372 \text{ l/h}$$

4. Calculate the result:
   Perform the multiplication:

   $$25 \times 58.993158480372 = 1474.8289620093$$

5. Result:

   $$25 \text{ Cubic inches per second} = 1474.8289620093 \text{ Litres per hour}$$

A quick way to check your answer is to estimate $25 \times 59 \approx 1475$, which is very close. This helps confirm the final value is reasonable.
