Factor1 mL = 0.01 dL
Converter
mL
Accepts numbers or expressions, e.g. 150 + 14.7
Result
dL
Rendered to 6 significant figures.
Formula
Formula
dL = mL × 0.01
Multiply any value in millilitres by 0.01 to obtain the value in decilitres.
Worked example
Convert 100 mL to dL.
- 01Start with 100 mL.
- 02Multiply by the conversion factor: 100 × 0.01 = 1 dL.
Result100 mL = 1 dL

FAQ
What is the conversion factor from mL to dL?
1 mL equals 0.01 dL. To convert, multiply the value in millilitres by 0.01.
How do I convert 1 mL to dL?
1 mL = 0.01 dL. For any value, multiply by 0.01.
How do I convert dL back to mL?
Divide by the same factor — or equivalently, multiply by 100. So 1 dL = 100 mL.
When would I need to convert millilitre to decilitre?
Volume conversions are used for tank sizing, batch calculations, and bridging between vendor specs (gallons, barrels, ft³) and process documentation (m³, litres).
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
