About Converting Liters per Millisecond to Quart per Days
Liter per Millisecond and Quart per Days 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 days = liters per millisecond × 91297861.295
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per millisecond equals 1 base unit, and 1 quart per days equals 1.095316e-8 base units, so dividing one by the other gives the direct liter per millisecond-to-quart per days factor of 91297861.295.
Simple example
1 L/ms × 91297861.29 = 91,297,861.29 qt/d
1 liter per millisecond = 91,297,861.29 quart per days.
Real-world example
60 L/ms × 91297861.29 = 5,477,871,678 qt/d
60 liters per millisecond = 5,477,871,678 quart per days.

Reverse conversion: Quart per Days to Liter per Millisecond
1 qt/d × 1.095316e-8 = 1.095316e-8 L/ms
1 quart per days = 1.095316e-8 liters per millisecond.
liters per millisecond = quart per days × 1.095316e-8

Frequently asked questions
How many quart per days are in 1 liter per millisecond?
1 liter per millisecond equals 91,297,861.29 quart per days, using the exact defined conversion factor rather than an estimate.
How do I convert liter per millisecond to quart per days?
Multiply the liter per millisecond value by 91297861.29. The converter above does this instantly to whatever precision you set.
How do I convert quart per days back to liter per millisecond?
Use the reverse factor: 1 quart per days equals 1.095316e-8 liters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per millisecond?
Liter per Millisecond (L/ms) is a unit of flow rate.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
Is the liter per millisecond to quart per days conversion exact?
Yes. Both liter per millisecond and quart per days are defined by fixed standards rather than physical artifacts, so the factor of 91297861.29 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.
