Understanding the Units
Fluid ounce per minute (fl‑oz/min) measures how many US fluid ounces flow each minute. One US fluid ounce equals 29.5735 milliliters, or 0.295735 decilitre.
Decilitre per second (dl/s) measures how many decilitres flow each second. One decilitre is 100 milliliters.
Exact Conversion Factor
The relationship is fixed:
1 fl‑oz/min = 0.0049289 dl/s
This factor comes from converting ounces to decilitres (0.295735 dl) and then dividing by 60 seconds per minute.
Step‑by‑Step Conversion Formula
To turn any fluid‑ounce‑per‑minute value into decilitres per second, multiply by the factor:
dl/s = (fl‑oz/min) × 0.0049289
Worked Example
Suppose a garden irrigation system delivers 15 fl‑oz/min. Using the formula:
- Multiply 15 by 0.0049289.
- 15 × 0.0049289 = 0.0739335 dl/s.
- Rounded to four decimal places, the flow is 0.0739 dl/s.
This tells you the system moves just under eight‑hundredths of a decilitre each second.
When This Conversion Matters
- Home brewing: Recipes often list water flow in fluid ounces per minute, but modern equipment may display rates in decilitres per second.
- Medical devices: IV pumps sometimes use US fluid ounces, while European standards prefer decilitres.
- Laboratory work: Precise fluid‑handling instruments report in metric units, making the conversion essential for cross‑border collaboration.
Fluid Ounce Per Minute to Decilitre Per Second Conversion Table
Each row applies the same rule: multiply fluid ounces per minute by 0.0049289 to obtain decilitres per second. Values are rounded to four decimal places.
| Fluid Ounce Per Minute (fl‑oz/min) | Decilitre Per Second (dl/s) |
|---|---|
| 1 fl‑oz/min | 0.0049 dl/s |
| 2 fl‑oz/min | 0.0099 dl/s |
| 5 fl‑oz/min | 0.0246 dl/s |
| 10 fl‑oz/min | 0.0493 dl/s |
| 20 fl‑oz/min | 0.0986 dl/s |
| 50 fl‑oz/min | 0.2464 dl/s |
| 100 fl‑oz/min | 0.4929 dl/s |
| 500 fl‑oz/min | 2.4645 dl/s |
