Gallons per hour (gal/h) to Fluid Ounces per second (fl-oz/s) conversion

Understanding Gallons per hour to Fluid Ounces per second Conversion

Gallons per hour ($\text{gal/h}$) and fluid ounces per second ($\text{fl-oz/s}$) are both units of volume flow rate, meaning they describe how much liquid moves through a system over time. Gallons per hour is commonly used for slower flow rates such as pumps, filters, irrigation, and fuel usage, while fluid ounces per second is useful for smaller, more immediate flow measurements.

Converting between these units helps compare systems that are rated differently, especially when equipment specifications, dispensing rates, or process measurements use different time scales and volume units.

Conversion Formula

The verified conversion relationship is:

$$1 \ \text{gal/h} = 0.03555555555556 \ \text{fl-oz/s}$$

So, to convert gallons per hour to fluid ounces per second:

$$\text{fl-oz/s} = \text{gal/h} \times 0.03555555555556$$

The reverse relationship is:

$$1 \ \text{fl-oz/s} = 28.125 \ \text{gal/h}$$

So, to convert fluid ounces per second to gallons per hour:

$$\text{gal/h} = \text{fl-oz/s} \times 28.125$$

Step-by-Step Example

Suppose a pump delivers $18 \ \text{gal/h}$.

Write the formula:

$$\text{fl-oz/s} = \text{gal/h} \times 0.03555555555556$$

Substitute the value:

$$\text{fl-oz/s} = 18 \times 0.03555555555556$$

Calculate:

$$18 \ \text{gal/h} = 0.64 \ \text{fl-oz/s}$$

This means a flow rate of $18$ gallons per hour is equal to $0.64$ fluid ounces per second.

Real-World Examples

• A small chemical dosing pump rated at $9 \ \text{gal/h}$ has a flow rate of $0.32 \ \text{fl-oz/s}$.
• A water filtration feed line operating at $22.5 \ \text{gal/h}$ corresponds to $0.8 \ \text{fl-oz/s}$.
• A low-flow irrigation injector delivering $45 \ \text{gal/h}$ equals $1.6 \ \text{fl-oz/s}$.
• A liquid transfer system running at $84.375 \ \text{gal/h}$ is the same as $3 \ \text{fl-oz/s}$.

Interesting Facts

• The gallon and the fluid ounce are both customary units of volume used in the United States, and the fluid ounce is defined as $1/128$ of a U.S. gallon. Source: Wikipedia - Fluid ounce
• Flow rate units such as gallons per hour are widely used in engineering and industrial settings because they combine a volume unit with a time unit, making them useful for describing pump output, fuel consumption, and process throughput. Source: NIST - SI Units

How to Convert Gallons per hour to Fluid Ounces per second

To convert Gallons per hour to Fluid Ounces per second, use the volume flow rate conversion factor between these two units. In this case, multiply the given value in gal/h by the factor for fl-oz/s.

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

   $$25 \text{ gal/h}$$

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

   $$1 \text{ gal/h} = 0.03555555555556 \text{ fl-oz/s}$$

3. Set up the multiplication: Multiply the given amount by the conversion factor so gallons per hour cancel properly.

   $$25 \text{ gal/h} \times \frac{0.03555555555556 \text{ fl-oz/s}}{1 \text{ gal/h}}$$

4. Calculate the result: Perform the multiplication.

   $$25 \times 0.03555555555556 = 0.8888888888889$$

5. Result:

   $$25 \text{ Gallons per hour} = 0.8888888888889 \text{ Fluid Ounces per second}$$

A quick way to check your work is to estimate: since $25 \times 0.036 \approx 0.9$, the result $0.8888888888889$ is reasonable. Keeping the conversion factor handy makes similar flow-rate conversions much faster.

What is the formula to convert Gallons per hour to Fluid Ounces per second?

To convert Gallons per hour to Fluid Ounces per second, multiply the flow rate in gal/h by the verified factor $0.03555555555556$. The formula is $\text{fl-oz/s} = \text{gal/h} \times 0.03555555555556$. This gives the equivalent flow in fluid ounces per second.

How many Fluid Ounces per second are in 1 Gallon per hour?

There are $0.03555555555556$ Fluid Ounces per second in $1$ Gallon per hour. This is the verified conversion factor for the page. It is useful as a base value for scaling larger or smaller flow rates.

Why would I convert Gallons per hour to Fluid Ounces per second?

This conversion is useful when comparing slow liquid flow rates in more detailed units. For example, it can help in beverage dispensing, lab measurements, irrigation systems, or small pump output where per-second readings are easier to interpret. Using fl-oz/s can make short-interval flow easier to understand.

How do I convert a larger Gallons per hour value to Fluid Ounces per second?

Take the number of Gallons per hour and multiply it by $0.03555555555556$. For example, the setup is $\text{gal/h} \times 0.03555555555556 = \text{fl-oz/s}$. This direct factor keeps the conversion simple and consistent.

Is the Gallons per hour to Fluid Ounces per second factor always the same?

Yes, the factor stays the same as long as you are using the same gallon and fluid ounce definitions for this converter. On this page, the verified relationship is $1 \text{ gal/h} = 0.03555555555556 \text{ fl-oz/s}$. That means every value in gal/h can be converted by the same multiplier.

Can I use this conversion for pumps and dosing systems?

Yes, this conversion is often helpful for equipment that delivers liquid continuously over time. Pump ratings may be listed in Gallons per hour, while dosing or control calculations may be easier in Fluid Ounces per second. Converting with $0.03555555555556$ helps match the unit to the application.
