## What is Flow Rate Conversion?

Flow Rate Conversion - Easily convert between various units of flow rate, whether it's volume-based, mass-based, or mole-based.

In the realms of physics and engineering, especially in the domains of fluid dynamics and hydrometry, volumetric flow rate (also referred to as volume flow rate, fluid flow rate, or volume velocity) signifies the volume of fluid that traverses a given point per unit of time. It's typically denoted by the symbol Q, with the SI unit being m³/s (cubic meters per second). Another unit occasionally used is sccm (standard cubic centimeters per minute).

In physics and engineering, mass flow rate represents the mass of a substance passing through a point per unit of time. It's measured in kilograms per second in SI units and in slug per second or pound per second in US customary units. The common symbol is ṁ (pronounced "m-dot"), although sometimes μ (Greek lowercase mu) is employed.

Occasionally, mass flow rate is referred to as mass flux or mass current, as seen, for instance, in Fluid Mechanics, Schaum's, and other references. In this article, we adopt the more intuitive definition.

### 3/5 — Feature suggestion

*2024-08-18*

I would love to be able to set favorite conversions that I do often to a home page. This would save time scrolling through the many many options for units.

### 1/5 — Look for a different solution.

*2019-05-04*

The scrolling of the units doesn’t lock but you still have to scroll the screen to see the answer so you have to be very careful of where you touch on the scree. 

Also if you go from mass to volume to mole it doesn’t keep your last used conversion for any of those categories so you have to scroll again. This is more of a pain. I’m going to look for something else to use. Wish I wouldn’t have paid for this.
