The micrometre (SI symbol: μm) is a unit of length in the metric system equal to 10 −6 metres ( 1 / 1 000 000 m = 0. 000 001 m). To help compare different orders of magnitude , this section lists some items with lengths between 10 −6 and 10 −5 m (between 1 and 10 micrometers , or μm).
The park is home to a famous, 157-hectare (390-acre) stand of ancient Douglas fir, known as Cathedral Grove, which draws visitors from all over the world. The park provides the only highway-accessible protected old-growth Douglas-fir forest in British Columbia. In 2007 Cathedral Grove made the short list on CBC's competition Seven Wonders of ...

LiDAR-derived height measurements were more accurate for ponderosa pine (-0.43 i: 0.13 m) than for Douglas-fir (-1.05 i: 0.41 m) at the narrow beam setting. Tree heights acquired using conventional field techniques (-0.27 2 0.27 m) were more accurate than those obtained using LiDAR (-0.73 i: 0.43 m for narrow beam setting).
The Lynn Valley Tree was one of the tallest known Coast Douglas-fir (Pseudotsuga menziesii var. menziesii), at a measured height of 126.5 meters (415 ft). [1] It was cut down by the Tremblay Brothers, at Argyle Road in 1902 on the property of Alfred John Nye in Lynn Valley, now part of metropolitan Vancouver, B.C. In 1912, Alfred Nye told ...
The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
Coast Douglas-fir seed cone, from a tree grown from seed collected by David Douglas Pseudotsuga menziesii var. menziesii has attained heights of 393 feet (120* m). That was the estimated height of the tallest conifer ever well-documented, the Mineral Tree ( Mineral, Washington ), measured in 1924 by Dr. Richard E. McArdle, [ 7 ] former chief of ...
