Litres per hour to Litres per second conversion

How to convert litres per hour to litres per second?

To convert from litres per hour (L/h) to litres per second (L/s), you need to recognize that there are 3600 seconds in an hour (since 1 hour = 60 minutes and 1 minute = 60 seconds, so 60 * 60 = 3600).

The relationship between litres per hour and litres per second is:

$\text{Litres per second} (L/s) = \frac{\text{Litres per hour} (L/h)}{3600}$

So, to convert 1 L/h to L/s:

$1 \, \text{L/h} = \frac{1 \, \text{L}}{3600 \, \text{s}} \approx 0.00027778 \, \text{L/s}$

Real-World Examples

1. Household Water Flow

A standard domestic faucet might have a flow rate of about 9.5 litres per minute (L/min), which is equivalent to:

$9.5 \, \text{L/min} \times 60 \, \text{min/hour} = 570 \, \text{L/h}$ To find the flow rate in litres per second: $570 \, \text{L/h} = \frac{570}{3600} \approx 0.1583 \, \text{L/s}$

2. Drip Irrigation Systems

A typical drip irrigation emitter might operate at a rate of 4 litres per hour. To convert this to litres per second: $4 \, \text{L/h} = \frac{4}{3600} \approx 0.0011 \, \text{L/s}$

3. Aquarium Water Pumps

An aquarium water pump might have a flow rate of around 1000 litres per hour. To convert this to litres per second: $1000 \, \text{L/h} = \frac{1000}{3600} \approx 0.2778 \, \text{L/s}$

4. Fire Hydrants

A fire hydrant can provide around 1500 litres per minute, which is: $1500 \, \text{L/min} \times 60 \, \text{min/hour} = 90{,}000 \, \text{L/h}$ To convert this to litres per second: $90{,}000 \, \text{L/h} = \frac{90{,}000}{3600} = 25 \, \text{L/s}$

Summary

To convert litres per hour to litres per second, always divide by 3600. This makes it simple to switch between these units as long as you remember that 1 hour = 3600 seconds.
