Fuminant dosage relationships

oz/1 000 ft³ =g/m³ = mg/litre (approximately)

OTHER CONVERSION FACTORS

Under practical conditions, use same figure for pounds per 1 000 bushels U.S. or Br (1 lb/1 000 U.S. bu = 1 032 lb/1 000 Br bu).

U.S. gal/1 000 U.S. bu to Br gal/1 000 Br bu x 0.86 (0.9 approximately)
Br gal/1 000 Br bu to U.S. gal/1 000 U.S. bu x 1.16
lb/1 000 Br bu tog/m³ x 12.47
lb/1 000 U.S. bu tog/m³ x 12.87
Br gal/1 000 Br bu to litre/m³ x 0.125

TEMPERATURE

Degrees Centigrade (°C) to degrees Fahrenheit = (°C x 1.8) + 32
Degrees Fahrenheit(°F) to degrees Centigrade = (°F - 32 ) x 0.55 (or x 5/9)
