Cubic Decimeters per second (dm³/s) to Cubic feet per hour (ft³/h) conversion

Converting between cubic decimeters per second and cubic feet per hour involves understanding the relationship between metric and imperial units of volume flow rate. This conversion is frequently used in fields like fluid dynamics, chemical engineering, and HVAC (Heating, Ventilation, and Air Conditioning).

Understanding the Conversion

The key to converting between these units lies in knowing the conversion factors between decimeters and feet, and seconds and hours. Remember that 1 cubic decimeter ($dm^3$) is equal to 1 liter, and a cubic foot ($ft^3$) is a volume measurement in the imperial system.

Conversion Factors

• 1 cubic decimeter ($dm^3$) = 0.0353147 cubic feet ($ft^3$)
• 1 second = 1/3600 hours

Converting Cubic Decimeters per Second to Cubic Feet per Hour

To convert from cubic decimeters per second ($dm^3/s$) to cubic feet per hour ($ft^3/h$), you need to multiply by the appropriate conversion factors:

1. Cubic Decimeters to Cubic Feet: Multiply by 0.0353147 to convert $dm^3$ to $ft^3$.
2. Seconds to Hours: Multiply by 3600 to convert seconds to hours.

Formula:

$$1 \frac{dm^3}{s} = 1 \frac{dm^3}{s} \times \frac{0.0353147 ft^3}{1 dm^3} \times \frac{3600 s}{1 h}$$

$$1 \frac{dm^3}{s} = 1 \times 0.0353147 \times 3600 \frac{ft^3}{h}$$

$$1 \frac{dm^3}{s} ≈ 127.133 \frac{ft^3}{h}$$

Therefore, 1 cubic decimeter per second is approximately equal to 127.133 cubic feet per hour.

Converting Cubic Feet per Hour to Cubic Decimeters per Second

To convert from cubic feet per hour ($ft^3/h$) to cubic decimeters per second ($dm^3/s$), you need to divide by the same conversion factors used above:

1. Cubic Feet to Cubic Decimeters: Divide by 0.0353147 to convert $ft^3$ to $dm^3$.
2. Hours to Seconds: Divide by 3600 to convert hours to seconds.

Formula:

$$1 \frac{ft^3}{h} = 1 \frac{ft^3}{h} \times \frac{1 dm^3}{0.0353147 ft^3} \times \frac{1 h}{3600 s}$$

$$1 \frac{ft^3}{h} = \frac{1}{0.0353147 \times 3600} \frac{dm^3}{s}$$

$$1 \frac{ft^3}{h} ≈ 0.00786574 \frac{dm^3}{s}$$

Therefore, 1 cubic foot per hour is approximately equal to 0.00786574 cubic decimeters per second.

How to Convert Cubic Decimeters per second to Cubic feet per hour

To convert Cubic Decimeters per second to Cubic feet per hour, multiply the flow rate by the unit conversion factor. In this case, use the factor between $\text{dm}^3/\text{s}$ and $\text{ft}^3/\text{h}$.

1. Write the given value:
   Start with the flow rate you want to convert:

   $$25\ \text{dm}^3/\text{s}$$

2. Use the conversion factor:
   The conversion factor is:

   $$1\ \text{dm}^3/\text{s} = 127.13286571572\ \text{ft}^3/\text{h}$$

3. Set up the multiplication:
   Multiply the given value by the conversion factor so the units change from $\text{dm}^3/\text{s}$ to $\text{ft}^3/\text{h}$:

   $$25\ \text{dm}^3/\text{s} \times 127.13286571572\ \frac{\text{ft}^3/\text{h}}{\text{dm}^3/\text{s}}$$

4. Calculate the result:

   $$25 \times 127.13286571572 = 3178.3216428931$$

5. Result:

   $$25\ \text{dm}^3/\text{s} = 3178.3216428931\ \text{ft}^3/\text{h}$$

If you are converting other values, use the same formula: multiply the number of $\text{dm}^3/\text{s}$ by $127.13286571572$. This is especially useful for comparing metric and imperial flow rates in engineering and HVAC applications.

What is the formula to convert Cubic Decimeters per second to Cubic feet per hour?

To convert Cubic Decimeters per second to Cubic feet per hour, multiply the value in $dm^3/s$ by the factor $127.13286571572$. The formula is $ft^3/h = dm^3/s \times 127.13286571572$. This gives the equivalent flow rate in Cubic feet per hour.

How many Cubic feet per hour are in 1 Cubic Decimeter per second?

There are exactly $127.13286571572$ Cubic feet per hour in $1$ Cubic Decimeter per second. This is the conversion factor used for the calculation. It is useful as a reference point for quick conversions.

Why would I convert Cubic Decimeters per second to Cubic feet per hour?

This conversion is commonly used when comparing flow rates between metric and imperial-based systems. It can help in HVAC, water treatment, industrial piping, and air flow reporting where equipment specifications may use different units. Converting to $ft^3/h$ makes the value easier to use in systems that follow imperial conventions.

Can I use this conversion for liquid and gas flow rates?

Yes, this is a unit conversion for volumetric flow rate, so it applies to both liquids and gases. The conversion only changes the units, not the physical properties of the substance being measured. As long as the original value is in $dm^3/s$, multiply by $127.13286571572$ to get $ft^3/h$.

Is Cubic Decimeters per second the same as liters per second?

Yes, $1$ Cubic Decimeter is equal to $1$ liter, so $1\ dm^3/s = 1\ L/s$. That means a flow rate given in $dm^3/s$ can be interpreted the same way as liters per second before converting. You can then use the factor $127.13286571572$ to express it in $ft^3/h$.

How do I convert a larger flow rate from Cubic Decimeters per second to Cubic feet per hour?

Multiply the number of Cubic Decimeters per second by $127.13286571572$. For example, if the flow rate is $10\ dm^3/s$, the result is $10 \times 127.13286571572\ ft^3/h$. This direct multiplication works for any value in $dm^3/s$.
