Discussion Overview

The discussion revolves around converting costs from USD per kilogram to USD per gallon for two liquids with specified costs and specific gravities. Participants explore the implications of specific gravity on the conversion and the potential need for temperature considerations.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant suggests that for water, 1 kg equals 1 liter, leading to a conversion of 120 USD/kg to approximately 454 USD/gallon, but notes that adjustments are needed for the specific gravity of liquid B.
  • Another participant challenges the conversion factor used, asserting that 1 gallon is about 4 liters, indicating a potential error in the previous calculation.
  • Some participants mention the importance of accounting for temperature when making precise conversions, suggesting that this could affect the density and thus the conversion accuracy.
  • There is a reiteration of the need to consider the specified density values provided by the original poster in the conversion process.

Areas of Agreement / Disagreement

Participants express differing views on the conversion factors and the implications of specific gravity, indicating that multiple competing views remain without a consensus on the correct approach.

Contextual Notes

There are unresolved issues regarding the accuracy of the conversion factors used, as well as the potential impact of temperature on the density of the liquids involved.

Hello,

How do i convert USD/kg to USD/gallon? pl help

Liquid A:
Cost=1416 USD/gallon
Specific Gravity=1.35

Liquid B:
Cost=120 USD/Kg
Specific Gravity=1.67

Thank you

If it was water (specific gravity = 1), then 1 kg = 1 liter, and since 1 gallon ≈ 3,785 liter, that's
120 USD/kg = 120 UDS/liter = 454 UDS/gallon

I'll let you make the adjustment for the specific gravity of liquid B.

I think you're off by a factor of 1000 on that conversion of gallons to liters. 1 gallon is about 4 liters.

That was a European "decimal point" :wink:
 
You may have to account for the temperature of the liquid depending on how precise your conversion needs to be.

In his first post, the OP specified the required density values.
