About Converting Imperial quart per Days to Quart per Seconds
Imperial 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 = imperial quart per days × 0.000013899883397
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per days equals 1.31542e-8 base units, and 1 quart per seconds equals 0.000946352946 base units, so dividing one by the other gives the direct imperial quart per days-to-quart per seconds factor of 0.000013899883397.
Simple example
1 imp qt/d × 0.0000138998834 = 0.0000138999 qt/s
1 imperial quart per days = 0.0000138999 quart per seconds.
Real-world example
60 imp qt/d × 0.0000138998834 = 0.000833993 qt/s
60 imperial quart per days = 0.000833993 quart per seconds.

Frequently asked questions
How many quart per seconds are in 1 imperial quart per days?
1 imperial quart per days equals 0.0000138999 quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per days to quart per seconds?
Multiply the imperial quart per days value by 0.0000138998834. The converter above does this instantly to whatever precision you set.
How do I convert quart per seconds back to imperial quart per days?
Use the reverse factor: 1 quart per seconds equals 71,943.04955 imperial quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per days?
Imperial quart per Days (imp 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 imperial quart per days to quart per seconds conversion exact?
Yes. Both imperial quart per days and quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0000138998834 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.
