Units explained
Liter
The liter is a metric unit of volume equal to one cubic decimeter (0.001 m³). It is the everyday metric volume unit.
Introduced in France in 1795; redefined in 1964 as exactly one cubic decimeter.
The world's common unit for beverages, fuel, and household liquids.
France, 1795; CGPM 1964.
Metric Teaspoon
A metric teaspoon is exactly 5 milliliters.
Adopted as the standard metric small cooking measure.
Universal in metric recipes and liquid medicine dosing.
Metrication.
Liter to Metric Teaspoon conversion formula
The relationship between liters and metric teaspoons:
To convert liters to metric teaspoons, multiply the value in liters by 200. To reverse, multiply metric teaspoons by 0.005.

Step-by-step: convert liters to metric teaspoons
- Write down the value in liters (L).
- Multiply that value by the factor 200.
- The product is the equivalent value in metric teaspoons (tsp).
- To reverse, multiply the metric teaspoon value by 0.005.
Worked examples
Example 1 — Convert 1 L to tsp:
1 × 200 = 200 tsp
Example 2 — Convert 100 L to tsp:
100 × 200 = 20000 tsp
Real-world example — Adjacent metric sub-units
One liter equals 1,000 metric teaspoons. Engineers move between these scales constantly: PCB feature sizes in the larger unit, wire-bond diameters in the smaller.
1 L × 200 = 200 tsp
Real-world example — Adjacent small-scale precision
One liter equals 1,000 metric teaspoons — the standard sub-millimeter precision conversion that materials engineers use whenever they switch between bulk material thickness specs (larger unit) and surface-finish characteristics (smaller unit).
1 L × 200 = 200 tsp
