WARNING: This product contains nicotine. Nicotine is an addictive chemical. For adults 21 and over only. See our age verification and responsible use policy.

Quick answer: To convert a vape's nicotine strength from percent to milligrams per milliliter, multiply by 10: 5% is about 50 mg/mL, 3% about 30 mg/mL, 2% about 20 mg/mL. To find the total nicotine in a device, multiply mg/mL by the e-liquid volume: a 5% disposable with 13 mL holds about 650 mg. Salt nic e-liquids usually come in 20 to 50 mg/mL; freebase in 3 to 12 mg/mL. Every product page lists the strength; compare devices with the charts below.

Percent to mg/mL

Label (%)	mg/mL	Usually found in
0%	0	Zero-nicotine products
0.3%	3	Freebase, sub-ohm kits
0.6%	6	Freebase
1.2%	12	Freebase, MTL kits
2%	20	Salt nic pods and disposables
3%	30	Salt nic
3.5%	35	Salt nic
5%	50	Salt nic, most disposables

The rule: percent times 10 equals mg/mL.

Total nicotine per device

E-liquid volume	At 2% (20 mg/mL)	At 5% (50 mg/mL)
2 mL pod	40 mg	100 mg
10 mL disposable	200 mg	500 mg
13 mL disposable	260 mg	650 mg
16 mL disposable	320 mg	800 mg
20 mL disposable	400 mg	1,000 mg
30 mL bottle	600 mg	1,500 mg

Formula: mg/mL times mL equals total mg.

Salt nic vs freebase

Salt nic is made for higher strengths in low-wattage pods and disposables; freebase is used at lower strengths in higher-wattage devices. More: salt nic vs freebase and the coil wattage chart.

Buying e-liquid?

Salt nic and freebase come in different strength ranges.

Puff count and nicotine

Puff counts are estimates; total nicotine depends on e-liquid volume and strength, not the puff number. See puff count in the vape glossary.

Reading labels

Look for the percent or mg/mL on the box and product page.
Check the e-liquid volume in mL.
Zero-nicotine products say 0% or 0 mg.
Every nicotine product carries the FDA nicotine warning.

Storage and children

Liquid nicotine is toxic if swallowed. Keep devices, pods and bottles away from children and pets, and dispose of them properly: how to dispose of a disposable vape.
