When working with densities and weights in different systems of measurement, it’s common to need conversions between units like grams per milliliter (g/mL) and pounds per cubic inch (lb/in³). These units are often used in fields like chemistry, engineering, and material science. Grams per milliliter is a metric unit, while pounds per cubic inch is part of the imperial system.

This guide will explain how to convert grams per milliliter (g/mL) to pounds per cubic inch (lb/in³) and why these conversions are important.

Why Convert Grams per Milliliter to Pounds per Cubic Inch?

The need for this conversion arises when working with different systems of measurement. In countries using the metric system, g/mL is the standard unit for density, while in others like the United States, pounds per cubic inch may be more familiar. By understanding how to convert between these units, professionals can work across different systems without confusion.

Conversion Formula: Grams per Milliliter to Pounds per Cubic Inch

To convert grams per milliliter (g/mL) to pounds per cubic inch (lb/in³), you need to multiply the number of grams per milliliter by the conversion factor 0.0361273.

Formula: 1 g/mL = 0.0361273 lb/in³

So, for instance:

• 1 g/mL = 0.0361273 lb/in³
• 2 g/mL = 0.0722546 lb/in³
• 5 g/mL = 0.1806365 lb/in³

Step-by-Step Guide: Converting Grams per Milliliter to Pounds per Cubic Inch

1. Identify the number of grams per milliliter you want to convert.
2. Multiply the number by 0.0361273.
3. The result will be in pounds per cubic inch.

Example Calculation

If you have a substance with a density of 3 g/mL, and you want to convert it to pounds per cubic inch:

3 g/mL × 0.0361273 lb/in³ = 0.1083819 lb/in³

So, a density of 3 g/mL equals 0.1084 lb/in³.
