About Converting Cubic Micrometers to Microliters
Cubic Micrometer and Microliter appear side by side at fuel pumps and on beverage labels, since the US measures liquids in gallons while most of the world uses liters. Specifically: Cubic metric volume unit, and microliter is 0.000001 liter units.
Formula
microliters = cubic micrometers × 1e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic micrometer equals 1e-18 base units, and 1 microliter equals 1e-9 base units, so dividing one by the other gives the direct cubic micrometer-to-microliter factor of 1e-9.
Simple example
1 um3 × 1e-9 = 1e-9 uL
1 cubic micrometer = 1e-9 microliters.
Real-world example
10 um3 × 1e-9 = 1e-8 uL
10 cubic micrometers = 1e-8 microliters.
Conversion table
| Cubic Micrometer (um3) | Microliter (uL) |
|---|---|
| 1 um3 | 1e-9 uL |
| 5 um3 | 5e-9 uL |
| 10 um3 | 1e-8 uL |
| 25 um3 | 2.5e-8 uL |
| 50 um3 | 5e-8 uL |
| 100 um3 | 1e-7 uL |
Reverse conversion: Microliter to Cubic Micrometer
1e-9 uL × 1000000000 = 1 um3
1e-9 microliters = 1 cubic micrometers.
cubic micrometers = microliters × 1000000000

Frequently asked questions
How many microliters are in 1 cubic micrometer?
1 cubic micrometer equals 1e-9 microliters, using the exact defined conversion factor rather than an estimate.
How do I convert cubic micrometer to microliter?
Multiply the cubic micrometer value by 1e-9. The converter above does this instantly to whatever precision you set.
How do I convert microliter back to cubic micrometer?
Use the reverse factor: 1 microliter equals 1,000,000,000 cubic micrometers. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic micrometer?
Cubic Micrometer (um3) is a unit of volume.
What is a microliter?
Microliter (uL) is a unit of volume.
Is the cubic micrometer to microliter conversion exact?
Yes. Both cubic micrometer and microliter are defined by fixed standards rather than physical artifacts, so the factor of 1e-9 used above is exact to as many digits as you choose to display.
