In summary, to convert from lb_f/in to N/m, you can use the conversion factor of 175.1268 N/m per lb_f/in. This allows for easier comparison and understanding of data across different systems of measurement. Online converters are available, but it is important to double-check the results. Context and application may affect the precision of the conversions. To check accuracy, use multiple conversion tools and have a basic understanding of the units and conversion factor.

Homework Statement


I am trying to find a damping ratio. I know ##k=50## lb##_f##/in, ##m=50## lb, ##c = 0.75## lb##_f##-sec/in.

Homework Equations


##1## lb##_f##/in = ##175.1268## N/m
##1## lb = ##0.4536## kg

The Attempt at a Solution


Then ##k = 8756.34## N/m, ##c = 131.345## N/m-sec, and ##m = 22.675## kg.
$$
\zeta = \frac{c}{2\omega_nm} = \frac{131.345}{2(0.00259)(22.675)} = 1000.26
$$
but this seems awfully large. Are my conversion factors incorrect?

Thanks. I divided m by k instead of the other way around.
 

FAQ: Converting from lb_f/in to N/m issues

How do I convert from lb_f/in to N/m?

To convert from pounds-force per inch (lb_f/in) to newtons per meter (N/m), you can use the conversion factor of 175.1268 N/m per lb_f/in. This means that for every 1 lb_f/in, there are 175.1268 N/m. So, to convert, you simply multiply the value in lb_f/in by 175.1268 to get the equivalent value in N/m.

Why do we need to convert between lb_f/in and N/m?

Lb_f/in and N/m are both units of force, but they are used in different systems of measurement. Lb_f/in is commonly used in the imperial system, while N/m is used in the metric system. Converting between these two units allows for easier comparison and understanding of data across different systems of measurement.

Can I use an online converter to convert between lb_f/in and N/m?

Yes, there are many online converters available that can easily convert between lb_f/in and N/m. However, it is always important to double-check the results and make sure the correct units are being used.

Are there any important considerations to keep in mind when converting between lb_f/in and N/m?

Yes, it is important to be aware of the context in which the conversions are being used. For example, lb_f/in is often used in engineering and construction, while N/m is commonly used in physics and mechanics. This means that the values and precision of the conversions may vary depending on the application.

How can I check if my conversions from lb_f/in to N/m are accurate?

One way to check the accuracy of your conversions is to use multiple conversion tools or methods and compare the results. Additionally, it is always helpful to have a basic understanding of the units and the conversion factor to ensure the correct calculations are being made.
