# Convert lb/hr to cc/min & cc/min to lb/hr

Fuel flow rate conversion is a critical aspect of engine operations, specifically in automotive engineering. One standard metric used is the pound per hour (lb/hr) flow rate, predominantly employed in the US. In other contexts, cubic centimetres per minute (cc/min) might be the norm. We will delve into these conversions, offering a comprehensive and accessible guide. So, sit tight, strap yourself in, and explore this fascinating topic!

## What Does Fuel Flow Rate Mean?

The fuel flow rate is a critical measure of how much fuel is consumed by an engine within a specific time frame. This concept is crucial when you're dealing with engines in any form. For instance, you might need the Carburetor CFM Calculator from CalciFI, which calculates the airflow that passes through a carburetor, expressed in cubic feet per minute (CFM). But what happens when the fuel flow rate is measured in lb/hr or cc/min?

## From Pounds Per Hour to Cubic Centimeters Per Minute

To kick things off, we need to grasp basic equality: 1 lb/hr (for gasoline) equals 10.50 cc/min in flow rate. This rate is the fundamental bedrock for converting lb/hr to cc/min. Let's break down the process:

Converting lb/hr to cc/min:

The formula to convert lb/hr to cc/min is pretty straightforward:

cc/min = lb/hr × 10.5

For example, if we want to convert 42 lb/hr to cc/min, we multiply 42 lb/hr by 10.5:

cc/min = 42 lb/hr × 10.5
cc/min = 441

## Converting Cubic Centimeters Per Minute to Pounds Per Hour

The magic of mathematics allows us to reverse the process as well, enabling the conversion from cc/min to lb/hr. We modify our initial formula to tackle this new challenge:

Converting cc/min to lb/hr:

lb/hr = cc/min ÷ 10.5

For instance, let's convert 1,692 cc/min to lb/hr. Here's how the calculation would look:

lb/hr = 1,692 ÷ 10.5
lb/hr = 161.142857

## Comparing lb/hr and cc/min

To make things even more transparent, we've prepared a conversion chart that indicates equivalent values in lb/hr and cc/min:

## Wrapping Up

While seemingly daunting at first, converting lb/hr to cc/min and vice versa is a straightforward process once you grasp the fundamental principles. So the next time you're faced with converting fuel flow rates, you'll know exactly what to do!

Whether you're an automobile enthusiast, an engineering student, or a seasoned mechanic, understanding these conversions will be helpful in your journey. So, keep exploring, keep learning, and remember - the world of automotive engineering is full of wonders waiting to be discovered!
