To learn to transfer meters to centimeters and to do the return operation, giving the sizes in centimeters to meters, very simply. The main thing is to remember how these sizes correspond among themselves.
How many in one meter of centimeters
Both the meter, and centimeter belong to the units of measure accepted by the International System of Units of SI. Measure length and distance in meters. It is possible to call meter conventional unit of measurement – in the 18th century its length was defined as 1⁄40 000 000 lengths of the Parisian meridian. Modern official determination of meter says that this distance which passes light in a vacuum for very small fraction of a second – 1/299,792,458 part.
And here the centimeter is the submultiple size "tied" to meter. Submultiple units are those which turn out at division of the "main" unit of measure into certain parts (shares). For example, the prefix "dets-" in the words "decimeter" or "decilitre" means that it is about the tenth part of meter or liter respectively. And "says sant-" that it is a one hundredth part of initial size.
Knowing that the prefix "designates sant-", it is easy to guess that the centimeter is a one hundredth part of meter. So, in one meter how many centimeters? Exactly 100.
Transfer of meters to centimeters – examples
If under the terms of a task it is necessary to result all linear sizes (width, length, height, growth and so on) in one value to transfer from meters to centimeters, it is necessary to increase value in meters by 100. Hundred – round number therefore process of multiplication will be simple and fast.
- Example 1. Height of a fence is 2 meters, it is necessary to calculate fence height in centimeters. To increase by the 100th, it is rather simple to add to it two zeroes. Means, as a result we receive that height of a fence equals 2х100 = 200 centimeters.
- Example 2. Vasya's growth – 1.35 meters. How many will it be in centimeters? If we multiply by the 100th decimal fraction, it is necessary to transfer the point separating the whole part from fractional to two signs to the right is and will be result of multiplication by hundred. Therefore if to transfer Vasya's growth from meters to centimeters, as a result we will receive 135 centimeters.
- Example 3. The snail in a day crept a distance in 5 meters and 8 centimeters. How many centimeters did the snail creep? We multiply the number of meters by 100 – as a result we receive 500, 500+8 = 508. Means, the route of a snail had the extent of 508 centimeters.
How to transfer centimeters to meters
To transfer centimeters to meters, it is necessary not to multiply any more, and to divide initial size into 100. Too it is easy to make it – in such cases in integers the last two signs separate a decimal point, in fractional – the point is transferred to two signs more to the left.
- Example 1. Length of a ruler is 120 centimeters. How many it meters? We separate the last two signs a decimal point, we receive 1.20. If the decimal fraction terminates on zero – they can just be rejected. Total as a result we receive that 120 centimeters are equal 1.2 meters.
- Example 2. Height of ceilings in the apartment – 308.5 centimeters, we will transfer this value to meters. We transfer a point to two signs to the right, we receive 3.085 meters.
- Example 3. Tail length at Muski's cat – 19 centimeters. Let's transfer from centimeters to meters. For this purpose we separate the last two signs, and before a comma we write a zero – 0.19 meters, zero whole 19 of the 100-th turn out. It is obvious that at us and the result less than unit, in one meter 100 centimeters had to turn out, and the tail at Muska is much shorter.
Thus, it is not much more difficult to transfer meters to centimeters, than to transfer centimeters to meters. The main thing not to forget that in meter of 100 centimeters - and reduction of linear sizes to some units of measure will never be a problem.
