A microgram is one of the smallest units of mass that is used. To convert milligrams to grams, multiply the milligram value by 0. For example, to convert mg to grams, multiply by 0. A microgram is a metric unit of mass that is equal to one thousandth of a milligram mg. In other words, a microgram is one thousand times smaller than a milligram.
No, 1, grams is greater than 1 kilogram. Are kilograms bigger or smaller than grams? Note that the names of all metric units follow from these three basic units. In the metric system, the basic unit of length is the meter. A meter is slightly larger than a yardstick, or just over three feet.
Among scientists, one gram is defined as the mass of water that would fill a 1-centimeter cube. Weight is a measure of the pull of gravity on an object. Though it is rarely necessary to convert between the customary and metric systems, sometimes it helps to have a mental image of how large or small some units are. The table below shows the relationship between some common units in both systems. The metric system is a base 10 system.
This means that each successive unit is 10 times larger than the previous one. The names of metric units are formed by adding a prefix to the basic unit of measurement. To tell how large or small a unit is, you look at the prefix. To tell whether the unit is measuring length, mass, or volume, you look at the base.
Here is a similar table that just shows the metric units of measurement for mass, along with their size relative to 1 gram the base unit. The common abbreviations for these metric units have been included as well. The prefixes have the same meanings whether they are attached to the units of length meter , mass gram , or volume liter.
Which of the following sets of three units are all metric measurements of length? All of these measurements are from the metric system. For instance, you can figure out how many centigrams are in one dekagram by using the table above. One dekagram is larger than one centigram, so you expect that one dekagram will equal many centigrams.
In the table, each unit is 10 times larger than the one to its immediate right. One gram is 1, times larger than a milligram, so you can move the decimal point in 3, three places to the left. Kilometers km are larger than centimeters cm , so you expect there to be less than one km in a cm.
Once you begin to understand the metric system, you can use a shortcut to convert among different metric units. The size of metric units increases tenfold as you go up the metric scale. The decimal system works the same way: a tenth is 10 times larger than a hundredth; a hundredth is 10 times larger than a thousandth, etc. By applying what you know about decimals to the metric system, converting among units is as simple as moving decimal points.
Here is the first problem from above: How many milligrams are in one decigram? You can recreate the order of the metric units as shown below:. This question asks you to start with 1 decigram and convert that to milligrams.
As shown above, milligrams is two places to the right of decigrams. The same method works when you are converting from a smaller to a larger unit, as in the problem: Convert 1 centimeter to kilometers.
There are 10 milliliters in a centiliter, 10 centiliters in a deciliter, and 10 deciliters in a liter. You used this method when you were converting measurement units within the U.
The factor label method works the same in the metric system; it relies on the use of unit fractions and the cancelling of intermediate units. The table below shows some of the unit equivalents and unit fractions for length in the metric system.
You should notice that all of the unit fractions contain a factor of Remember that the metric system is based on the notion that each unit is 10 times larger than the one that came before it. Also, notice that two new prefixes have been added here: mega- which is very big and micro- which is very small. When applying the factor label method in the metric system, be sure to check that you are not skipping over any intermediate units of measurement! Using the factor label method, write 7, cm as a fraction and use unit fractions to convert it to m.
If you have a prescription for 5, mg of medicine, and upon getting it filled, the dosage reads 5g of medicine, did the pharmacist make a mistake? Learning how to solve real-world problems using metric conversions is as important as learning how to do the conversions themselves.
Mathematicians, scientists, nurses, and even athletes are often confronted with situations where they are presented with information using metric measurements, and must then make informed decisions based on that data. The first step in solving any real-world problem is to understand its context. This will help you figure out what kinds of solutions are reasonable and the problem itself may give you clues about what types of conversions are necessary.
Here is an example. Marcus bought at 2 meter board, and cut off a piece 1 meter and 35 cm long. How much board is left? Start by calculating how much water will be used in a week using the factor label method to convert the time units. This problem asked for the difference between two quantities. The easiest way to find this is to convert one quantity so that both quantities are measured in the same unit, and then subtract one from the other.
A bread recipe calls for g of flour. How many kilograms of flour would you need to make 5 loaves? So a kilo is 2. Length Mass Volume meter gram liter other units you may see kilometer kilogram dekaliter centimeter centigram centiliter. The gram and kilogram are two units used to measure mass in the metric system. From the gram , we get the rest of the metric units using the standard metric prefixes. Metric Units. Milligram mg 0. Kilograms to Milligrams conversion 1 gram kg is equal to milligrams mg.
A kg is not times larger than a gram. It's times as large. Symbol: ng. Pounds to kg conversion 1 pound lb is equal to 0. Answer: Sava kilo is equal to 1. Step-by-step explanation: Sava is a hindi word which means quarter to a value. Therefore, sava kilo is equal to 1. What weighs 5 grams? Wendy Krieger, designs measurement for many bases. The water in a teaspoon would do, but if you live in the USA, you can make 5 grams out of two dimes, or a nickel 5c.
Dimes, quarters, and half-dollars are 'silver money', of which a dollar is a metric ounce of 25 g. Kilogram kg , basic unit of mass in the metric system. A kilogram is very nearly equal it was originally intended to be exactly equal to the mass of 1, cubic cm of water.
