About Converting Quart per Days to Liter per Hours
Quart per Days and Liter per Hours 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
liter per hours = quart per days × 0.03943137275
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 liter per hours equals 2.777778e-7 base units, so dividing one by the other gives the direct quart per days-to-liter per hours factor of 0.03943137275.
Simple example
1 qt/d × 0.03943137275 = 0.0394313728 L/h
1 quart per days = 0.0394313728 liter per hours.
Real-world example
60 qt/d × 0.03943137275 = 2.365882365 L/h
60 quart per days = 2.365882365 liter per hours.

Frequently asked questions
How many liter per hours are in 1 quart per days?
1 quart per days equals 0.0394313728 liter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert quart per days to liter per hours?
Multiply the quart per days value by 0.03943137275. The converter above does this instantly to whatever precision you set.
How do I convert liter per hours back to quart per days?
Use the reverse factor: 1 liter per hours equals 25.36051703 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 liter per hours?
Liter per Hours (L/h) is a unit of flow rate.
Is the quart per days to liter per hours conversion exact?
Yes. Both quart per days and liter per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.03943137275 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.
