How the Methanol Converter Works
The Methanol Converter divides methanol mass by methanol density at the measuring temperature. The default 0.791 kg/L fits pure methanol at 20°C (68°F).
Check the temperature
Methanol density falls about 0.00094 kg/L per °C of warming.
Pick the density
Read the density for your temperature from the table.
Enter the mass
Type the methanol weight in kilograms.
Read the liters
Use the volume for tanks, drums and dosing pumps.
Methanol Converter Formula
The methanol formula is V = m ÷ ρ(T), with ρ(T) ≈ 0.810 − 0.00094 × T for T in °C.
- T
- Methanol temperature, °C
Worked Examples
- At 20°C: 1,000 kg ÷ 0.7914 = 1,263.6 L.
- At 40°C: 1,000 kg ÷ 0.7724 = 1,294.7 L, 31 L more.
- Race fuel can: 20 L × 0.791 = 15.82 kg.
Methanol Converter Conversion Table

What is a Methanol Converter?
A Methanol Converter is a calculator that converts methanol weight into volume using methanol density at a set temperature.
Methanol (CH₃OH) is the simplest alcohol. Industry makes about 100 million tonnes a year from natural gas or coal through synthesis gas.
Methanol is toxic: 30 mL can be fatal for an adult. Methanol feeds formaldehyde, acetic acid and biodiesel production, and fuels racing engines and fuel cells.
What are the Uses of a Methanol Converter?
There are 4 main uses of a Methanol Converter.
Biodiesel production
Producers convert methanol kg into reactor liters.
Chemical plants
Operators convert tank tonnage into volume.
Motorsport fuel
Teams convert fuel weight into tank fills.
Wastewater denitrification
Plants dose methanol by volume from mass targets.
