A gram g is a unit of mass, one of the basic units of CGS. There is also a decimal fraction of the base unit of mass in the International System of Units SI in kilograms.
A centigram cg is a decimal fraction of the basic unit of mass in the International System of Units SI , kilograms. Inches of mercury inHg and Hg are a unit of pressure. It is used for atmospheric pressure in weather reporting, refrigeration, and aviation in the United States. The kilogram abbreviation, kg is the unit of mass in the international standard SI system of units. It was originally defined as the mass of one liter cubic meters of pure water.
M stands for meter in the metric system of measurement. One meter equals one hundred centimeters and one thousand millimeters. The CG Workwear brand is synonymous with high quality workwear in the hospitality industry.
Particularly interesting are the aprons, which are mainly produced in Germany. CG International GmbH sells its brand collections throughout Europe through qualified business partners and wholesalers. What does CG mean the same way? As can be seen, the centigram is a very small unit of measurement relative to units of mass that are used to measure many everyday objects.
For example, a person who weighs 60 kilograms weighs 6,, centigrams, so discussing mass in terms of kilograms is more convenient. This is one of the benefits of SI; values can easily be expressed using units that denote various multiples of 10, so a person can easily adjust the units used to present data that reflects the desired magnitude.
This is part of the reason that centigrams are not widely used for everyday measurements; they are more likely to be used in laboratory settings for precise measurements of mass. Another reason centigrams may not be commonly used is because grams and milligrams are two other units of mass that are used relatively frequently, both of which are similar in magnitude to centigrams.
You could convert either measurement. Understanding the context of real-life application problems is important. Look for words within the problem that help you identify what operations are needed, and then apply the correct unit conversions. The metric system is an alternative system of measurement used in most countries, as well as in the United States. The metric system is based on joining one of a series of prefixes, including kilo-, hecto-, deka-, deci-, centi-, and milli-, with a base unit of measurement, such as meter, liter, or gram.
Units in the metric system are all related by a power of 10, which means that each successive unit is 10 times larger than the previous one. This makes converting one metric measurement to another a straightforward process, and is often as simple as moving a decimal point.
It is always important, though, to consider the direction of the conversion. If you are converting a smaller unit to a larger unit, then the decimal point has to move to the left making your number smaller ; if you are converting a larger unit to a smaller unit, then the decimal point has to move to the right making your number larger. The factor label method can also be applied to conversions within the metric system.
To use the factor label method, you multiply the original measurement by unit fractions; this allows you to represent the original measurement in a different measurement unit. If you have been to other countries, though, you may notice that meteorologists measure heat and cold differently outside of the United States. The difference is that the two countries use different temperature scales.
A temperature of. Celsius Fahrenheit. A cook puts a thermometer into a pot of water to see how hot it is. Which temperature scale is the thermometer measuring? By looking at the two thermometers shown, you can make some general comparisons between the scales.
Sometimes, it is necessary to convert a Celsius measurement to its exact Fahrenheit measurement or vice versa. For example, what if you want to know the temperature of your child in Fahrenheit, and the only thermometer you have measures temperature in Celsius measurement?
Converting temperature between the systems is a straightforward process as long as you use the formulas provided below. How were these formulas developed? They came from comparing the two scales. Notice how these fractions are used in the conversion formulas.
What temperature does water boil at in the Fahrenheit scale? A Celsius temperature is given. To convert it to the Fahrenheit scale, use the formula at the left. A Fahrenheit temperature is given. To convert it to the Celsius scale, use the formula at the left. The next example shows how these formulas can be used to solve a real-world problem using different temperature scales. Two scientists are doing an experiment designed to identify the boiling point of an unknown liquid.
Which temperature is higher and by how much? To find the difference between them, we need to measure them on the same scale. Whichever way you choose, it is important to compare the temperature measurements within the same scale, and to apply the conversion formulas accurately.
What is the average temperature in degrees Fahrenheit? Temperature is often measured in one of two scales: the Celsius scale and the Fahrenheit scale. You can use conversion formulas to convert a measurement made in one scale to the other scale. Skip to main content.
Module 3: Measurement. Search for:. Learning Objectives In this lesson you will learn how to do the following: Describe the general relationship between the U. Convert from one temperature scale to the other, using conversion formulas. Try It Now Which of the following sets of three units are all metric measurements of length? A inch, foot, yard B kilometer, centimeter, millimeter C kilogram, gram, centigram D kilometer, foot, decimeter Show Answer B kilometer, centimeter, millimeter All of these measurements are from the metric system.
Example How many milligrams are in one decigram? Show Answer Identify locations of milligrams and decigrams. Dg is 10 times larger than a cg, and a cg is 10 times larger than a mg. Try It Now Convert 3, milligrams to grams. Show Answer One gram is 1, times larger than a milligram, so you can move the decimal point in 3, three places to the left. Example Convert 1 centimeter to kilometers.
Show Answer Identify locations of kilometers and centimeters. Cm is 10 times smaller than a dm; a dm is 10 times smaller than a m, etc.
Since you are going from a smaller unit to a larger unit, divide.
