Understanding the Phrase: What “King Henry Died by Drinking Chocolate Milk” Really Means
The phrase “King Henry Died by Drinking Chocolate Milk” is a mnemonic device designed to help students remember the sequence of metric prefixes. Each word in the phrase stands for a specific unit in the metric system, organized from largest to smallest:
- King = Kilo (1,000 units)
- Henry = Hecto (100 units)
- Died = Deka (10 units)
- By = Base unit (meter, gram, or liter — 1 unit)
- Drinking = Deci (0.1 units)
- Chocolate = Centi (0.01 units)
- Milk = Milli (0.001 units)
This phrase helps learners recall the metric order, which is crucial when performing conversions between units. Whether you’re dealing with liters, grams, or meters, this trick works for all base metric measurements.
Why the Metric System Is Worth Understanding
The metric system is a globally adopted measurement system, with only a few countries like the United States not using it as the default. Designed around powers of ten, it’s one of the simplest and most logical ways to measure and convert quantities.
Here’s why the metric system is so efficient:
- Base-10 Structure: Every step up or down in the metric scale is a multiple or division of ten.
- Global Standard: Used in science, medicine, and almost every country worldwide.
- Ease of Conversion: With tools like “King Henry Died by Drinking Chocolate Milk”, converting units becomes second nature.
For instance, converting meters to kilometers simply involves moving the decimal three places to the left. The structure of the metric system is logical, and the mnemonic adds a layer of simplicity.
The Origins of the Metric System and the Rise of the Mnemonic
While the phrase “King Henry Died by Drinking Chocolate Milk” is modern and fun, the metric system has historical roots. It was developed in France during the late 1700s. The goal was to establish a universal system of measurement that people across countries could understand and use consistently.
The phrase itself was created by educators, not scientists. Teachers saw that students struggled to remember the sequence of units, so they created easy-to-remember sentences like this one. Its quirky, memorable nature is what makes it so effective in classrooms around the world.
Real-World Application: How to Use “King Henry Died by Drinking Chocolate Milk”
Let’s break down how to apply this mnemonic when converting units:
Step-by-Step Guide:
- Identify the Starting Unit: What unit are you beginning with?
- Locate the Target Unit: What unit are you converting to?
- Count the Steps: Use the mnemonic to count how many places you move on the metric scale.
- Move the Decimal: Shift the decimal point left or right depending on whether you’re moving up or down the scale.
Example 1:

Examples of Metric Conversions Using the Mnemonic
Let’s apply the phrase to real conversion examples:
1. Kilograms to Grams
From Kilo (King) to Base (By)
Three steps right → move decimal three places right
1 kg = 1,000 g
2. Meters to Centimeters
From Base (By) to Centi (Chocolate)
Two steps right → move decimal two places right
1 m = 100 cm
3. Liters to Milliliters
From Base (By) to Milli (Milk)
Three steps right → move decimal three places right
1 L = 1,000 mL
4. Millimeters to Meters
From Milli (Milk) to Base (By)
Three steps left → move decimal three places left
1,000 mm = 1 m
Using “King Henry Died by Drinking Chocolate Milk” for these conversions ensures you’re on the right track.
