The method to convert microliters (μL) to milliliters (mL) is demonstrated in this worked example problem.

## Problem

Express 6.2 x 10^{4} microliters in milliliters.

## Solution

1 μL = 10^{-6} L

1 mL = 10^{-3} L

Set up the conversion to the desired unit will be canceled out. In this case, we want mL to be the remaining unit.

Volume in mL = (Volume in μL) x (10^{-6} L/1 μL) x (1 mL/10^{-3} L)

Volume in mL = (6.2 x 10^{4} μL) x (10^{-6} L/1 μL) x (1 mL/10^{-3} L)

Volume in mL = (6.2 x 10^{4} μL) x (10^{-6}/10^{-3} mL/μL)

Volume in mL = (6.2 x 10^{4} μL) x (10^{-3} mL/μL)

Volume in mL = 6.2 x 10^{1} μL or 62 mL

## Answer

6.2 x 10^{4} μL = 62 mL
