Here are the conversion factors for those various expressions of wind speed: 1 m/s = 2.237 statute mile/h = 1.944 knots 1 knot = 1.151 statute mile/h = 0.514 m/s 1 statute mile/h = 0.869 knots = 0.447 m/s. Note: 1 statute mile = 5,280 feet = 1,609 meters
At 10 000 ppm the solution is a deep red colour. As the concentration decreases the colour becomes orange, then a vibrant yellow, with the final 1 ppm sample a very pale yellow. In science and engineering , the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities , e.g. mole fraction or ...
The conversion equations depend on the temperature at which the conversion is wanted (usually about 20 to 25 °C). At an ambient sea level atmospheric pressure of 1 atm (101.325 kPa or 1.01325 bar), the general equation is:

The LD 50 to rats through the oral exposure route is 366 mg/kg. [7] In regards to occupational exposures to n-butylamine, the Occupational Safety and Health Administration and National Institute for Occupational Safety and Health have set occupational exposure limits at a ceiling of 5 ppm (15 mg/m 3) for dermal exposure. [8]
The values presented below are from Annex 1, Table 1, "Groundwater target values and soil and groundwater intervention values". In previous versions of the Dutch Standards, target values for soil were also present. However, in the 2009 version, target values for soils have been deleted for all compounds except metals.
The table at right is based on the kilogram (kg), the base unit of mass in the International System of Units . The kilogram is the only standard unit to include an SI prefix (kilo-) as part of its name. The gram (10 −3 kg) is an SI derived unit of mass.
1-nitropropane is toxic to humans and can cause damage to the kidneys and liver. The vapours are irritating for the lungs and eyes and the maximum exposure rate is 25 ppm. [1] It is not known to be a carcinogen.
