Answer key: Teaspoons to Milliliters worksheet

1. In US teaspoons: 0.2 tsp
1. The official definition goes the other way: 1 tsp is exactly 4.92892159375 mL
  $1 tsp$ $= 4.92892159375 mL$
2. So divide your milliliters by 4.92892159375 to get US teaspoons
  $\frac{1 mL}{4.92892159375}$ $= 0.202884136211 tsp$
3. Or multiply by 0.202884136211 instead. It gives the same answer, because 1 ÷ 4.92892159375 ≈ 0.202884136211
  $1 mL \times 0.202884136211$ $= 0.202884136211 tsp$
2. In milliliters: 4.93 mL
1. Start with the conversion factor: 1 tsp is exactly 4.92892159375 mL
  $1 tsp$ $= 4.92892159375 mL$
2. Multiply your US teaspoons by 4.92892159375 to get milliliters
  $1 tsp \times 4.92892159375$ $= 4.92892159375 mL$
3. In milliliters: 14.79 mL
1. Start with the conversion factor: 1 tsp is exactly 4.92892159375 mL
  $1 tsp$ $= 4.92892159375 mL$
2. Multiply your US teaspoons by 4.92892159375 to get milliliters
  $3 tsp \times 4.92892159375$ $= 14.7867647813 mL$
4. In US teaspoons: 0.81 tsp
1. The official definition goes the other way: 1 tsp is exactly 4.92892159375 mL
  $1 tsp$ $= 4.92892159375 mL$
2. So divide your milliliters by 4.92892159375 to get US teaspoons
  $\frac{4 mL}{4.92892159375}$ $= 0.811536544844 tsp$
3. Or multiply by 0.202884136211 instead. It gives the same answer, because 1 ÷ 4.92892159375 ≈ 0.202884136211
  $4 mL \times 0.202884136211$ $= 0.811536544844 tsp$
5. In milliliters: 9.86 mL
1. Start with the conversion factor: 1 tsp is exactly 4.92892159375 mL
