About Teaspoon (US)
The US teaspoon is 1/6 US fluid ounce (about 4.9289 ml). US recipes use teaspoons for spices and small liquid amounts.
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.
How to convert teaspoons (us) to liters
1 teaspoon (us) is equal to 0.00492892159375 liter:
1 tsp = (0.00492892159375 L ÷ 1 L) l = 0.00492892159375 l
Each teaspoon (us) is defined as 0.00492892159375 L and each liter as 1 L, so one tsp equals 0.00492892159375 ÷ 1 l = 0.00492892159375 l.
Let V(tsp) be the numeric value of the same volume measured in Teaspoon (US) (tsp), and V(l) the value in Liter (l). Then:
V(l) = V(tsp) × (0.00492892159375 / 1)
Equivalently, divide by how many tsp fit into one l (liters per l divided by liters per tsp):
V(l) = V(tsp) ÷ 202.88413621105798
Or: liter = teaspoon (us) ÷ 202.88413621105798
Examples
Example #1: Convert 20 tsp to liter
20 tsp = 20 tsp × (0.00492892159375/1) l = 0.0985784319 l
20 tsp = 20 tsp ÷ 202.88413621105798 = 0.0985784319 l
Example #2: Convert 50 tsp to liter
50 tsp = 50 tsp × (0.00492892159375/1) l = 0.2464460797 l
50 tsp = 50 tsp ÷ 202.88413621105798 = 0.2464460797 l
Summary
To convert Teaspoon (US) to Liter, multiply the value in tsp by the ratio of liters per tsp divided by liters per l. Equivalently: value_l = value_tsp × (0.00492892159375 / 1). Numerically, 1 tsp equals 0.00492892159375 l.
Relationship context
You are converting between US customary fluid / volume (Teaspoons (US)) and metric (SI) (Liters). US and UK fluid measures differ (gallons, ounces, tablespoons); metric liters and cubic meters align with SI. The numeric factor used here is 4.928922e-3.
