About Converting Quart per Days to Metric teaspoon per Years
Quart per Days and Metric teaspoon per Years 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
metric teaspoon per years = quart per days × 69129.6631759
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 metric teaspoon per years equals 1.584437e-13 base units, so dividing one by the other gives the direct quart per days-to-metric teaspoon per years factor of 69129.6631759.
Simple example
1 qt/d × 69129.66318 = 69,129.66318 metric tsp/yr
1 quart per days = 69,129.66318 metric teaspoon per years.
Real-world example
60 qt/d × 69129.66318 = 4,147,779.791 metric tsp/yr
60 quart per days = 4,147,779.791 metric teaspoon per years.

What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
What is a metric teaspoon per years?
Metric teaspoon per Years (metric tsp/yr) is a unit of flow rate.
Is the quart per days to metric teaspoon per years conversion exact?
Yes. Both quart per days and metric teaspoon per years are defined by fixed standards rather than physical artifacts, so the factor of 69129.66318 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.
