Discussion Overview

The discussion centers around the interpretation of the abbreviation "Mg" in a scientific context, specifically in relation to the weight of a humpback whale mentioned in a question. Participants explore the meaning of "Mg" and its implications for weight measurement, including conversions between units.

Discussion Character

  • Technical explanation, Conceptual clarification

Main Points Raised

  • One participant questions whether "Mg" stands for Newton, leading to a clarification that Newton is represented by [N].
  • Another participant notes that "Mg" could be interpreted as Mega (M) and gram (g), suggesting it represents megagrams.
  • A calculation is presented to convert the weight of the whale from megagrams to grams, then to kilograms, and finally to Newtons, indicating a weight of approximately 53955 N.
  • A subsequent response confirms the calculation presented by the previous participant.

Areas of Agreement / Disagreement

Participants generally agree on the interpretation of "Mg" as megagrams and the subsequent calculations related to weight, but the initial question about its meaning in relation to Newton remains somewhat ambiguous.

Contextual Notes

The discussion does not explicitly address potential assumptions about the context in which "Mg" is used or the definitions of the units involved.

I'm reading this question that says "The 5.5-Mg humpback whale is stuck on the shore
due to changes in the tide..."

Does Mg mean Newton?
 
Physics news on Phys.org
Nope.

Newton is [N], but Mg doesn't look like N does it? :confused:

But Mega is [M] and gram is [g]... :smile:

You're so smart :smile: thanks!
 
So according to my conversation the whale weighs

5.5 x 1000000 = 5500000grams
5500000 / 1000 = 5500 kg

5500 x 9.81 = 53955 [N]

Yes?
