However, it is difficult to make large objective lenses (greater than 4 inches or 10 centimeters) for refractors. Refractors are relatively expensive, if you consider the cost per unit of aperture. Because the aperture is limited, a refractor is less useful for observing faint, deep-sky ...

A dime is 1.25mm thick. How many meters high would a stack of dimes worth $50 be? How many twenty dollar bills equal two thousand one hundred and fifty? How many centimeters are in a meter? How many inches in 3 meters? How many inches are ...
How many millimeters are in 10 centimeters? How many atoms are present in 1 gram of carbon-12? How many square feet are in one square meter? What is the expanded notation form of 21,853? How many baseballs are used in a game? How many ridges are on a dime? How many ridges on a...
The average diameter of an atom is 0.1 to 0.5 nanometers. One meter contains 1,000,000,000 nanometers. Smaller units, such as centimeters and millimeters, typically used to measure small objects that can fit within your hand, are still much larger than a nanometer. To carry this further,...
Inspired by a thru-hiker looking to track snow depths along the Pacific Crest Trail with Gaia GPS, the Snow Depth overlay gives you an estimate of snow levels covering your next route. Outdoor adventurers can examine how many centimeters of snow most likely exist in specific areas by referenci...

The meter is broken down into 100 centimeters which are about the diameter of an M&M (Smarties are 1.5 centimeters). A centimeter is broken down into 10 millimeters which are about the thickness of a dime. On the other side, 1000 meters is a kilometer. It takes the average person 12 ...
In 1887, a rancher named Matt Coleman spotted huge snowflakes that had fallen onto one of his cattle pastures in western Montana during a snowstorm and declared them as "larger than milk pans." With a width of 15 inches (38 centimeters) and a thickness of nearly 8 inches (20 cm), these...
