Unit Conversion (Length, Weight, Temperature, Volume)

Explanation of Numerical Units in the Book

Most units mentioned in D&D are Imperial (e.g., feet, inches, etc.). For ease of reading and reference, this book does not frequently use the term "feet" explicitly, but the units referred to remain the Imperial "feet" rather than the Chinese "chi." Please do not confuse them.

In addition, the following are some common DND units and their conversion ratios to other units. They will appear throughout the book; if you have any doubts about the units, you can check this page for quick confirmation:

1. Units of Length

1 foot = 12 inches

1 mile ≈ 5,280 feet

1 foot ≈ 0.3048 meters (1 meter ≈ 3.37 feet)

1 inch ≈ 2.54 centimeters (1 centimeter ≈ 0.3937 inches)

1 mile ≈ 1.6093 kilometers (1 kilometer = 1,000 meters ≈ 0.6214 miles)

(Note: All "feet," "inches," and "miles" mentioned in the book refer to Imperial units.)

2. Units of Weight

1 pound = 16 ounces

1 pound ≈ 453.59 grams (1 kilogram ≈ 2.204 pounds)

1 ounce ≈ 28.35 grams (1 kilogram ≈ 35.274 ounces)

(Note: All "pounds" mentioned in the book refer to Imperial units.)

3. Units of Temperature

y degrees Fahrenheit (℉) = 32 + x degrees Celsius (℃) × 1.8

y degrees Celsius (℃) = (x degrees Fahrenheit (℉) - 32) ÷ 1.8

4. Units of Volume

1 cubic foot ≈ 2.832 cubic decimeters = 0.02832 cubic meters (1 cubic meter ≈ 35.3147 cubic feet)

1 gallon ≈ 3.79 liters (1 liter ≈ 0.264 gallons)

1 pint (liquid) ≈ 0.473 liters (1 liter ≈ 2.113 pints (liquid))

1 pint (dry) ≈ 0.550 liters (1 liter ≈ 1.816 pints (dry))

(Note: All "pints" mentioned in the book refer to U.S. customary units, not Imperial units.)

5. Currency

1 gold piece (GP) = 10 silver pieces (SP) = 100 copper pieces (CP)

1 gold piece (GP) = 2 electrum pieces (EP)

1 platinum piece (PP) = 10 gold pieces (GP)
