Tornadoes are assigned ratings based on the severity of the damage they cause, which is used to estimated wind speed. The analysis is rather subjective, so the ratings can't really be defined as units. In the United States, wind speeds are usually estimated to the nearest 5 miles per hour (mph). Other countires usually do estimates in kilometers per hour (km/h). Scientific studies usually report speeds in meters per second (m/s).
That is impossible as the Richter scale is for measuring earthquakes.
The Joule.
caliore is the unit of measuring energy.
There is no scale for measuring how long a tornado's duration. It is simply stated how many minutes the tornado lasted if a figure is available.
An API unit is a unit of radioactivity used for measuring natural gamma rays in the ground.
Poise is a measuring unit of Viscosity.
A kilogram is a unit of measuring weight.
For measuring WHAT?
The SI unit for measuring weight (the force due to gravity) is the newton.The SI unit for measuring mass is the kilogram.
another unit for measuring distances is AU (Astronmical Unit)
The SI unit for measuring temperature is Kelvinkelvin kelvin
There is no particular instrument used for measuring tornado intensity. Ratings are based primarily on damage assessment. Occasionally doppler radar has measure wind speeds inside a tornado, but such measurements are rare.
Byte=8 Bits, is the basic data measuring unit.
The Enhanced Fujita Scale rates the strength of a Tornado by the damage it has caused!
league of measuring land
The basic unit is Hertz.
No, I think there is no unit for measuring sharpness.
