Frequently asked questions
What is the source unit in this conversion?
The source unit is us quarts per second (qt/s). The US Quart (qt) is a unit of volume. The Second (s) is a unit of time.
What is the destination unit in this conversion?
The destination unit is cubic kilometers per year (km3/yr). The Cubic Kilometer (km3) is a unit of volume. The Year (yr) is a unit of time.
How do I convert us quarts per second to cubic kilometers per year?
Multiply the us quarts per second value by 2.9864e-5 to get cubic kilometers per year. For example, 10 qt/s × 2.9864e-5 = 0.00029864 km3/yr.
Is the us quarts per second to cubic kilometers per year conversion exact?
It's exact under the SI-based volume and time definitions used here, since both units convert to cubic meters per second through fixed, non-rounded factors.
Where is this conversion commonly used?
Flow rate conversions like this are used in plumbing, HVAC, irrigation, chemical processing, fuel and water metering, and engineering flow calculations.
Can I convert cubic kilometers per year back to us quarts per second?

About this conversion
This page converts us quarts per second (qt/s) into cubic kilometers per year (km3/yr), two units of volumetric flow rate.
The US Quart (qt) is a unit of volume. The Second (s) is a unit of time.
The Cubic Kilometer (km3) is a unit of volume. The Year (yr) is a unit of time.
The formula is km3/yr = qt/s × 2.9864e-5, based on the fixed relationship between these two flow rate units.
Flow rate is calculated as a volume unit divided by a time unit, so every combination of a volume unit and a time unit forms a valid, exact flow rate unit.
