Which is the best unit for measuring each mass? mg = milligrams g = grams kg = kilograms
a. Amount of spices in a batch of cookies: mg g kg
b. Your mass: mg g kg
c. Mass of 10 pennies: mg g kg
A kg is about 2.2 pounds. Here are the other relations.
The metric system has prefix modifiers that are powers of 10.
A kilogram is 1000 grams
A hectogram is 100 grams
A decagram is 10 grams
A gram is the basic unit of mass
A decigram is 1/10 gram
A centigram is 1/100 gram
A milligram is 1/1000 gram
I hope this helps you come to your own answers. Thanks for asking.
To determine the best unit for measuring each mass, we need to consider the magnitude of the mass being measured and choose a unit that is appropriate for that scale.
a. Amount of spices in a batch of cookies: Since spices are typically used in small quantities, milligrams (mg) would be the most suitable unit for measuring the mass of spices in a batch of cookies. Therefore, the answer is mg.
b. Your mass: When measuring personal mass, we typically use the unit kilograms (kg) as it provides a more practical and convenient measurement. Grams (g) can also be used, but kilograms are commonly used to represent human body weight. Therefore, the answer is kg.
c. Mass of 10 pennies: Pennies are relatively small objects, but they have a measurable mass. Grams (g) would be the most appropriate unit to measure the mass of 10 pennies since it provides a reasonable measurement scale. Therefore, the answer is g.
