About Liter
The liter is a metric unit equal to one cubic decimeter (0.001 m³). Science, global food labeling, and most countries’ everyday volumes use liters.
About Cup (UK)
The UK metric cup is often taken as 250 ml in modern recipes, though traditional imperial cups differ; this converter uses the liter-based UK cup factor from the shared table.
How to convert liters to cups (uk)
1 liter is equal to 3.5195079727854 cup (uk):
1 l = (1 L ÷ 0.284130625 L) ukcup = 3.5195079727854 ukcup
Each liter is defined as 1 L and each cup (uk) as 0.284130625 L, so one l equals 1 ÷ 0.284130625 ukcup = 3.5195079727854 ukcup.
Let V(l) be the numeric value of the same volume measured in Liter (l), and V(ukcup) the value in Cup (UK) (ukcup). Then:
V(ukcup) = V(l) × (1 / 0.284130625)
Equivalently, divide by how many l fit into one ukcup (liters per ukcup divided by liters per l):
V(ukcup) = V(l) ÷ 0.284130625
Or: cup (uk) = liter ÷ 0.284130625
Examples
Example #1: Convert 20 l to cup (uk)
20 l = 20 l × (1/0.284130625) ukcup = 70.3901594557 ukcup
20 l = 20 l ÷ 0.284130625 = 70.3901594557 ukcup
Example #2: Convert 50 l to cup (uk)
50 l = 50 l × (1/0.284130625) ukcup = 175.975398639 ukcup
50 l = 50 l ÷ 0.284130625 = 175.975398639 ukcup
Summary
To convert Liter to Cup (UK), multiply the value in l by the ratio of liters per l divided by liters per ukcup. Equivalently: value_ukcup = value_l × (1 / 0.284130625). Numerically, 1 l equals 3.519507972785404 ukcup.
Relationship context
You are converting between metric (SI) (Liters) and UK imperial fluid / volume (Cups (UK)). US and UK fluid measures differ (gallons, ounces, tablespoons); metric liters and cubic meters align with SI. The numeric factor used here is 3.519508e+0.
