Volume Conversion Guide

Cheat Sheet
  • 1 L = 1000 mL
  • 1 m³ = 1000 L
  • 1 US gal = 3.78541 L
  • 1 Imp gal = 4.54609 L
  • 1 US cup = 236.588 mL
  • 1 US fl oz = 29.5735 mL
  • 1 Imp pint = 568.261 mL
  • 1 ft³ = 28.3168 L

Note: US and Imperial (UK) measures differ (e.g., US gal 3.785 L vs Imp gal 4.546 L).

How conversions are calculated

We convert through a base unit (liter, L). Your input is first turned into liters using a precise factor, then from liters to the target unit. This two-step method keeps results consistent (e.g., US gal → L → mL).

Examples: 1 US cup × 236.588 = 236.588 mL; 2 ft³ × 28.3168 = 56.6336 L; 0.5 m³ × 1000 = 500 L.
When to use which unit
  • mL / L: beverages, medicine doses, lab work (metric).
  • US tsp / tbsp / cup / fl oz / pt / qt / gal: cooking & packaging (US customary).
  • Imperial pint / quart / gallon: UK recipes & older references.
  • m³ / ft³ / yd³: room/tank volumes, shipping, concrete/soil.
