Average length is 27.5 inches (70 cm).assasauga rattlesnakes range from central New York and southern Ontario west to the prairies of Iowa and Missouri. The eastern massasauga is strongly associated with wetlands across most of its range. Wet prairie is the preferred habitat in the west, bogs and swamps in the east.
Zeptometer is a length measurement unit. A zeptometer (zm) is a derived metric measurement unit of length. The metric unit prefix zepto means one sextillionth, or one (1) with twenty (20) nulls in front of it, i.e. 0.000,000,000,000,000,000,001 or 1Ã10 -21. That makes one zeptometer equal to one sextillionth of a meter.
Barometer - A barometer measures atmospheric pressure. A barometer can help to forecast upcoming weather based on the changes it measures in the atmospheric pressure. Some AcuRite weather stations feature a barometric pressure history chart or a pressure trend arrow so you can easily track changes, like a pressure drop. Anemometer - An anemometer measures how fast the wind is blowing, or wind speed. AcuRite weather stations can display wind speed in MPH, KPH or knots, and record current, peak and average wind speed readings. Wind Vane - A wind vane, or weather vane, is an instrument that determines which direction the wind is blowing.
