I really hope someone has an answer to this.Thnx(:

This is a King Henry Died By Drinking Chocolate Milk,Table.I am totally lost in this.

There is no question. Just a list of multiple choices. For what?

I suggest you study this site.

Then, post any specific questions you have about the metric system.

Based on the given letter to units of measurement correspondence, it appears to be a mnemonic or a memory aid to remember the metric prefixes and their corresponding symbols.

Let's break it down:

K: KILOGRAM
K represents "kilo," which is a metric prefix meaning 1,000 times. Therefore, K stands for kilogram, which is equal to 1,000 grams.

H: HECTOGRAM
H represents "hecto," which is a metric prefix meaning 100 times. Therefore, H stands for hectogram, which is equal to 100 grams.

D: DECAGRAM
D represents "deca," which is a metric prefix meaning 10 times. Therefore, D stands for decagram, which is equal to 10 grams.

B: BASE
B doesn't represent a specific metric unit, but rather stands for the base unit, which is "gram" in this case. The base unit is the standard unit of measurement for mass in the metric system.

D: DECIGRAM
D (again) represents "deci," which is a metric prefix meaning 0.1 times. Therefore, D stands for decigram, which is equal to 0.1 grams.

C: CENTIGRAM
C represents "centi," which is a metric prefix meaning 0.01 times. Therefore, C stands for centigram, which is equal to 0.01 grams.

M: MILLIGRAM
M represents "milli," which is a metric prefix meaning 0.001 times. Therefore, M stands for milligram, which is equal to 0.001 grams.

Overall, this mnemonic provides a way to remember the metric prefixes and their corresponding symbols for measuring mass.
