Frequently Asked Questions
-
What does petagram per second measure?
-
Petagram per second (Pg/s) is a unit for mass flow representing the movement of one petagram (10^15 grams) of mass every second.
-
Why convert Pg/s to lb/s?
-
Converting Pg/s to pounds per second allows expressing very large mass flow rates in a unit commonly used in engineering and industrial fields.
-
Are there any challenges using this conversion?
-
Yes, because Pg/s values are extremely large, corresponding lb/s numbers can be very large and may require careful handling in calculations.
Key Terminology
-
Petagram per second (Pg/s)
-
A mass flow unit equal to 10^15 grams transported every second, used for very large mass fluxes in scientific fields.
-
Pound per second (lb/s)
-
An imperial unit of mass flow rate describing how many pounds of mass pass a point each second, widely used in engineering.
