About Converting Quart per Days to Quart per Seconds
Quart per Days and Quart per Seconds both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
quart per seconds = quart per days × 0.0000115740740741
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per days equals 1.095316e-8 base units, and 1 quart per seconds equals 0.000946352946 base units, so dividing one by the other gives the direct quart per days-to-quart per seconds factor of 0.0000115740740741.
Simple example
1 qt/d × 0.00001157407407 = 0.0000115741 qt/s
1 quart per days = 0.0000115741 quart per seconds.
Real-world example
60 qt/d × 0.00001157407407 = 0.0006944444 qt/s
60 quart per days = 0.0006944444 quart per seconds.

Frequently asked questions
How many quart per seconds are in 1 quart per days?
1 quart per days equals 0.0000115741 quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert quart per days to quart per seconds?
Multiply the quart per days value by 0.00001157407407. The converter above does this instantly to whatever precision you set.
How do I convert quart per seconds back to quart per days?
Use the reverse factor: 1 quart per seconds equals 86,400 quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
What is a quart per seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
Is the quart per days to quart per seconds conversion exact?
Yes. Both quart per days and quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.00001157407407 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
