Convert. 1.0 L to uL.
1,000,000 uL
Note:
- L is a basic unit (including meter and gram), so the factor is 10^0.
- u has a factor of 10^6.
- To convert larger unit to smaller unit, get the difference of the exponents and move decimal to the right.
- If smaller unit to larger unit, move decimal to the left.
