grain per cubic foot

To convert degrees Celsius to degrees Fahrenheit: °C (9/5) + 32 = °F

To convert degrees Fahrenheit to degrees Celsius: (5/9) (°F − 32) = °C

For solutes in water: 1 mg/liter 1 ppm (by weight)

Atmospheric contamination: 1 mg/liter 1 oz/1000 cu ft (approx)

For gases or vapors in air at 25°C and 760 mm Hg pressure:

To convert mg/liter to ppm (by volume): mg/liter (24,450/mol. wt.) = ppm

To convert ppm to mg/liter: ppm (mol. wt./24,450) = mg/liter

Factors for conversion of some units

Mg/L × 28.32 = Mg/cubic foot

Mg/L × 1000 = Mg /cubic meter

Mg/cubic foot × 35.314 = Mg/cubic meter

Mg/cubic meter × 0.2832 = Mg/cubic foot
