            Length and Distance

            Length refers to the measurement of an object from one end to another, while distance is the space between two objects or points. The two systems used to measure length and distance are the English and metric systems.

            What instrument measures length or distance?

            User Avatar
            It depends on the meaning of length. Typically it means a unit of distance but it can also be applied to the passage of time, such as the duration of a piece of music. Thus a time-piece, such as a stopwatch, would be the instrument of choice when measuring a length of time. For units of distance, there are a huge number of instruments available: Calipers and micrometers Rulers and meter or yard sticks or line gauges tape measures, surveyor's wheels, micrometers, rangefinders laser rules. Walking wheels RADAR SONAR LIDAR Which instrument you use largely depends on how accurate the result needs to be (the tolerance), combined with the size of the object or the distance being measured. Generally, the greater the distance, the greater the tolerance. Measuring tapes are more flexible than straightedge rulers and can accurately measure much greater distances, typically up to 10m. Today, they are made from cloth or fiberglass (such as a tailor's measure) or from a stiff, curved metallic ribbon that can retract into a coil (such as a carpenter's or constructor's measure). Surveyor's tapes are often made from durable plastic or fiberglass and allow more accurate measuring over much greater distances, usually up to 100m or more. Micrometers are used when measuring the size of distant objects. Modern micrometers are often GPS-based systems used to perform geodetic measurements. Micrometers and calipers are generally used in engineering applications where straightedge rulers would be impractical, such as when measuring the diameter of a column or when measuring the gauge of a threaded bolt. Laser rulers are a new type of measuring device, designed to specifically measure the distance to an object, where a laser beam can be reflected back to the device. Handheld devices are generally low-power devices so their accuracy is limited to within 100m or so, but more powerful lasers can measure greater distances, including the distance to the moon (where reflectors were specifically placed during the moon landings in the late 60's and early 70's). In microscopes, there is commonly a glass slide marked with an engraving that goes down to a few microns (micrometer scale). The glass slide with the engraved lines is known as a graticule or reticule). To measure distance traveled, a pedometer is carried by walkers to measure distance walked. An Odometer is fitted to vehicles, including bicycles, to measure distances traveled (miles or kilometers). You may use a ruler. Examples of common instruments used for measuring length are the ruler, (for measuring milimeters, centimeters, inches, and 1 foot), the yardstick, (which is 3 feet long, [36 inches], and measures milimeters, centimeters, inches, and about 1 meter, {3.28084 feet}). There are also tape measurers that can measure all of the previously listed measurements and vary on the longest length they can measure. Units of length are based on feet or meters. Tools for measuring length range from simple rulers to lasers. A ruler I would say a ruler or a tape measure.

            5 km is exactly 3.10685596 miles (don't forget that extra .00685596 of a mile, it could cost you the race). That comes out to be 3 miles + 564 feet + 2.4 inches.

            How many centimetres are there in 8.5 inches?

            User Avatar
            21.59 centimeters. Solution: 1. 2.54 centimeters = 1 inch. You can express this as the fraction 2.54 cm / 1 inch (read aloud as "2.54 centimeters per inch") 2. To convert 8.5 inches to centimeters, cancel the inches in the numerator and denominator & multiple 2.54 * 8.5 = 21.59 cm (see below. Note: Disregard the _ character. It is only included to make the fractions align properly for easier viewing. 2.54 cm__8.5 inches___ 21.59 cm --------- * ----------- = ----------- = 21.59 cm 1 inch_______1__________1

            The area of one acre is 43,560 square feet, but there are an infinite number of different shapes and dimensions an acre could have. Here are a few examples: Square: 208.71 feet on a side (approx.) Rectangles: 9' x 4840' 10' x 4356' 12' x 3630' 20' x 2178' 24' x 1815' 40' x 1089' 60' x 726' 72' x 605' 120' x 363' 121' x 360' 180' x 242' Circle: 235.5-ft diameter (approx.) All 13 of these examples have areas of 1 acre. One Acre = 43560 sq ft

            Note that "kilo-" means "a thousands of a unit". Then, 1 km = 1,000 meters. Therefore: 50,000 meters is 50 kilometers.

            There are 1000 meters in a kilometer. The prefix kilo- means "1000". Examples: kilogram is one thousand grams kilohertz is one thousand oscillations per second kilovolt is one thousand volts kilobyte is roughly one thousand bytes of storage (used because 210, or 1024, is the power of two closest to 1000 bytes: it is easily close enough to one thousand, or one kilo-, for describing computer storage in general terms).

            User Avatar
            There are 10 millimeters in 1 centimeter. Prefix 'milli' is used to denote sub multiples of meter and uses factor 0.001. Prefix 'centi' is used to denote sub multiples of meter and uses factor 0.01. Factor difference of 10 (0.01 / 0.001 = 10) shows that there are 10 millimeters in one centimeter. 10 ten 1 cm = 10 mm Ten (10).

            58 cm equals how many inches?

            User Avatar
            Inch and cm are used for measuring the distances. To convert the centimeters to inch we have to multiply the cm unit to 0.393701. This will convert the distance from cm to inch. The answer to the above question is 22.834 inches(approximately).

            How many pixels are in a 2 feet by 2 feet photo?

            User Avatar
            That would depend on the resolution of the printing. If for example, it is 100 pixels per inch, then 2 ft = 24 in (times 100 pix per inch) = 2400 x 2400 = 5,760,000 ***** From a mathematical perspective, the answer is sound. From a photography perspective, the asker should know that it is a relationship between the "resolution" that the image was taken at versus the size of the viewed image. The reason for the quotes is in my last sentence. In a 640x320 image (A), there are twice as many pixels in both directions than one of 320x160 (B). Therefore, the A image is twice the length and height as the B image and the pixels and spaces between are no different in size from one picture to the other. Thus there is no difference in the eye's ability to "resolve" the spaces in between for a given viewing distance. What does matter is the size that the images are rendered at. To make this as simple as possible, it is best to compare photographs printed from these two images. An 8x10 from A will look better because there are more pixels crammed in a given inch than there will be in picture B, thus your eye's ability to resolve the spaces between them is not as good. So how many pixels are in an inch for a GIVEN photo size depends on the "resolution" of the image file versus the size it is viewed at. The "resolution of the printing" is a matter for the printer or machine that creates the print, and that is another animal altogether. The problem is, pixel count is not supported as a measure of digital photograph resolution by international standards even though it is used by just about everybody. Hopefully, my answer sheds some light as to why.
