133.7 gal to nL round 4 significant figure

To convert 133.7 gallons to nanoliters (nL), we first need to convert gallons to liters, then convert liters to nanoliters.

1. Conversion factor from gallons to liters:
   \[
   1 \, \text{gal} = 3.78541 \, \text{L}
   \]
   So,
   \[
   133.7 \, \text{gal} = 133.7 \times 3.78541 \, \text{L} = 505.857417 \, \text{L}
   \]

2. Conversion factor from liters to nanoliters:
   \[
   1 \, \text{L} = 1 \times 10^9 \, \text{nL}
   \]
   So,
   \[
   505.857417 \, \text{L} = 505.857417 \times 10^9 \, \text{nL} = 5.05857417 \times 10^{11} \, \text{nL}
   \]

3. Rounding to four significant figures:
   \[
   5.05857417 \times 10^{11} \, \text{nL} \approx 5.059 \times 10^{11} \, \text{nL}
   \]

Thus, 133.7 gallons is approximately \( 5.059 \times 10^{11} \, \text{nL} \).
