Convert acetone volume to weight, such as liters or gallons to kg or lb, using its 0.791 g/mL density at 20°C, or convert weight back to volume and moles.

Temperature and density
Default 20°C. This constant-expansion model is limited to 0–40°C.

Retained model assumption: 0.00143/°C. Use verified material data for precision; zero disables temperature correction.

Acetone Weight Formula

Acetone mass equals volume multiplied by density. The default is approximately 0.791 g/mL at 20°C, so 30 mL has an estimated mass of 23.73 g. Optional temperature correction uses density(T) = density20 / [1 + beta(T – 20°C)]; the retained beta of 0.00143 per °C is an adjustable approximation limited here to 0–40°C. Use verified material data for precision.

ACW = AV × density(T)

Variables:

  • ACW is the Acetone Weight (grams)
  • AV is the total volume of acetone (mL) 

How to Calculate Acetone Weight?

The following steps outline how to calculate the Acetone Weight.

  1. First, determine the total volume of acetone (mL). 
  2. Next, choose the units and check the temperature and density settings. At the default 20°C setting, use ACW = AV * 0.791 when AV is in mL and ACW is in grams.
  3. Finally, calculate the Acetone Weight.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total volume of acetone (mL) = 30

ACW = 30 * 0.791 = 23.73 g (at the default 20°C setting)
