Thought-Process to Discover Knowledge

Welcome to nubtrek.

Books and other education websites provide "matter-of-fact" knowledge. Instead, nubtrek provides a thought-process to discover knowledge.

In each of the topic, the outline of the thought-process, for that topic, is provided for learners and educators.

This topic provides a very brief overview of conversion of Units of Measure.

Length of an object is the distance-span of the object from one end to the other end. To specify the distance-span the standard-unit meter is defined.

What is the standard unit of measure for length?

  • meter
  • meter
  • height

The answer is "meter"

The distance between two cities is `200000` meter. It is noted that the number is very large in some applications.

Which of the following help in simplifying such large values?

  • it cannot be simplified
  • a larger measure of length is defined such as `1` kilometer = `1000` meter.
  • a larger measure of length is defined such as `1` kilometer = `1000` meter.

The answer is "a larger measure of length is defined". Using the larger measure, the distance between two cities is given as `200` kilometer.

The length of a pen is very small to measure in `1` meter. It is noted that the number is very small in some applications.

Which of the following help in simplifying such small values?

  • it cannot be simplified
  • a smaller measure of length is defined such as `1` meter = `100` centimeter.
  • a smaller measure of length is defined such as `1` meter = `100` centimeter.

The answer is "a smaller measure of length is defined". Using the smaller measure, the length of a pen is given as `7` centimeter.

The basic unit "meter" is converted into smaller or larger units of lengths.

`1000` millimeter = `1` meter

`100` centimeter = `1` meter

`10` decimeter = `1` meter

`1` decameter = `10` meter

`1` hectometer = `100` meter

`1` kilometer = `1000` meter Remember the following:
"milli" is from a Latin root word meaning thousand
"centi" is from a Latin root word meaning hundred
"deci" is from a Latin root word meaning tenth
"deca" is from a Greek root word meaning ten
"hecto" is from a Greek root word meaning hundred
"kilo" is from a Greek root word meaning thousand


Among these, millimeter, centimeter, meter, and kilometer are widely used depending on the scale of the length measurement.
