How many 0.5 equal 2 mg?
It depends on 0.5 measured in what units. The number of 0.5 grams in 2 mg will be different from the number of 0.5 nanograms, for example.
What are exact numbers and measured numbers?
Exact numbers are values that are counted or defined, such as the number of students in a classroom or defined quantities like 100 centimeters in a meter. They have no uncertainty and are considered infinitely precise. Measured numbers, on the other hand, arise from measurements and include inherent uncertainty due to limitations in the measuring instrument or technique, such as the length of an object measured with a ruler. For example, if a ruler indicates a length of 5.3 cm, that number is a measured number with a degree of uncertainty.
Where can you find the estimated digit on a measured number?
A measured number is not estimated. It is measured to the accuracy of the tool being used, though all tools have a certain tolerance and the last digit would be the least accurate.
What is measured or tested by the data collected in a experiment?
There are many different things that are measured and tested by the data collected in an experiment. Color changes are one thing that can be measured and tested for example.
What will the number of times the sun will rise in two years be measured by?
It can be measured in days, weeks or months

What is the number of measured quantity 351g?
The number of the measured quantity is 351 grams.
Is ml a measured number or an exact number?
Milliliters (abbreviated "ml") is generally a measured quantity.
What is the difference between a measured digit and an exact number?
Hi! Wow, good question! In chemistry, an exact number is one that you know is absolutely true. For example, these are exact numbers: 12 inches in a foot 9 roses 1000mg in 1 g However, a measured number is one that needs significant figures. For example, these are measured numbers: 12.3 g 1001 liters 361.3 miles These are numbers that you aren't absolutely sure. If you weigh something and it states 3.0 grams, that is NOT an exact number, but rather a measured number. For all you know, the weight may be 3.00000003, but since the weighing scale can only show two digits, you get 3.0 g. Good luck!

What is an observation that can be measured or counted?
One example of an observation that can be measured or counted is the number of times a car horn is sounded in a busy intersection over a period of time. This observation can be quantified by tallying the occurrences to analyze patterns or behaviors.
How is pressur measured?
It is measured with a barometer.force per area ( for example pounds per square inch)
What substance is not measured on a pH?
For example a solid metal.
How are radio wavelengths measured?
The frequency, or number of cycles per second is measured, then divide the speed of light in meters per second (299,792,458) by frequency to get wavelength in meters. Example: 7 Mhz = 7,000,000 hz 299792458 / 7000000 = 42.8 meters.
How many times can electricity be measured?
There is no limit to the number of times electricity could be measured.
What is an example of something that would be measured in meters?
The diameter of your mothers panties, nah Jk. In the United States, nothing is measured in meters but everywhere else HEIGHT is a good example.
