Homework Help Overview

The discussion revolves around a conversion problem involving the density of a substance given in kg/m³ that needs to be converted to slugs/gal. The original poster expresses difficulty in understanding the conversion process, particularly due to their lack of prior physics experience.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the need to clarify the units involved in the conversion, questioning the original poster's understanding of the relationship between kilograms and slugs, as well as cubic meters and gallons. Some suggest specific conversion factors while others emphasize the need to verify the approach taken.

Discussion Status

There is an ongoing exploration of the conversion factors needed for the problem. Some participants have provided specific values for conversions, while others have pointed out potential misunderstandings in the method being applied. The conversation reflects a mix of guidance and clarification without reaching a definitive conclusion.

Contextual Notes

The original poster has indicated a lack of experience in physics, which may influence their understanding of the problem and the conversions involved. There is also a potential confusion regarding the operations (multiplication vs. division) necessary for the conversion process.

I think you want to convert kg/m3 right?

Well 1 kg is how many slugs?

How many m3 are in a gal?

1 kg=0.068521 slug
1 gal =0.003785 m^3

(6.21*10^3) kg /m^3= (6.21*10^3) *(0.068521)*0.003785 slug/gal

right so 1 kg=0.068521 slug and 1m3 = 264.172052358. You are converting 1 kg/ 1 m3. So you are correct in what you are doing, but you need to divide, not multiply.
