To convert from teaspoons (t) to milliliters (mL), we need to use the conversion factor that 1 teaspoon is approximately equal to 4.92892 milliliters. Therefore, we can multiply the number of teaspoons by this conversion factor to get the equivalent volume in milliliters.
Step 1: Conversion Factor
To convert from teaspoons to milliliters, we use the conversion factor:
\[
1 \, \text{t} \approx 4.92892 \, \text{mL}
\]
Step 2: Calculation
Given that \(3 \, \text{t}\) needs to be converted to milliliters, we perform the following calculation:
\[
\text{milliliters} = 3 \, \text{t} \times 4.92892 \, \text{mL/t} = 14.78676 \, \text{mL}
\]
Step 3: Rounding
Rounding \(14.78676\) to four significant digits gives us:
\[
14.79 \, \text{mL}
\]
