Litre to Gallon: A Comprehensive Conversion Guide for Fluid Measurement

Introduction

Understanding the relationship between litres and gallons is crucial for anyone involved in fluid measurement, from everyday household tasks to industrial applications. This guide provides a comprehensive overview of litre to gallon conversions, including conversion formulas, tables, and practical applications.

Understanding the Units

• Litre (L): A unit of volume in the metric system, equal to 1,000 cubic centimetres.
• Gallon (gal): A unit of volume in the imperial system, defined as follows:
  • 1 US gallon (US gal) = 3.785 litres
  • 1 imperial gallon (imp gal) = 4.545 litres

Conversion Formulas

To convert litres to gallons:
* US gallons (US gal) = Litres x 0.26417
* Imperial gallons (imp gal) = Litres x 0.21997

To convert gallons to litres:
* Litres = US gallons (US gal) x 3.7854
* Litres = Imperial gallons (imp gal) x 4.5461
