From the Guidelines
32 millimoles (mmol) of caffeine is equivalent to 6,218.88 milligrams (mg). To convert from millimoles to milligrams, you need to multiply the number of millimoles by the molecular weight of the substance. Caffeine has a molecular weight of 194.19 g/mol 1, which equals 194.19 mg/mmol. Therefore, 32 mmol × 194.19 mg/mmol = 6,214.08 mg of caffeine. This calculation is based on the molecular weight of caffeine, not directly related to the provided evidence on ascorbic acid conversion 1. For context, a typical cup of coffee contains about 95 mg of caffeine, and most health authorities suggest limiting caffeine consumption to 400 mg per day for healthy adults. Consuming 6,214.08 mg of caffeine would be extremely dangerous and potentially fatal, as it's more than 15 times the recommended daily limit. Key points to consider:
- The molecular weight of caffeine is crucial for this conversion
- The provided evidence 1 does not directly apply to this calculation, as it pertains to ascorbic acid
- The calculated amount of caffeine exceeds safe consumption limits by a significant margin
From the FDA Drug Label
Each mL contains 20 mg caffeine citrate (equivalent to 10 mg of caffeine base) The molecular weight of caffeine is not directly provided, however, the molecular formula of caffeine is 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione, which can be used to calculate its molecular weight. The molecular weight of caffeine can be calculated as follows:
- C8H10N4O2 = 812.01 + 101.008 + 414.01 + 216.00 = 194.19 g/mol To convert 32 mmol of caffeine to milligrams, we use the molecular weight of caffeine. 32 mmol * 194.19 mg/mmol = 6214 mg
From the Research
Caffeine Measurement Conversion
To convert 32 millimoles (mmol) of caffeine to milligrams (mg), we need to know the molar mass of caffeine. The molar mass of caffeine is approximately 194.19 g/mol.
Calculation
- 1 mmol of caffeine is equal to 194.19 mg (since 1 mmol = 1 millimole = 0.001 moles, and the molar mass of caffeine is 194.19 g/mol)
- Therefore, 32 mmol of caffeine is equal to 32 x 194.19 mg = 6214.08 mg
Relevant Studies
There are no direct studies provided that discuss the conversion of mmol to mg of caffeine. However, studies such as 2, 3, and 4 discuss the effects of caffeine intake and measurement, but do not provide a direct conversion factor. Study 5 provides information on standard values for caffeine content in food products, but does not discuss the conversion of mmol to mg.
