This guide explains the exact conversion value, formula, step-by-step calculation, examples, and frequently asked questions in simple and easy-to-understand language.

Quick Answer

1 Scruple (apothecary) = 12.95978 Decigrams

Conversion Formula:

Decigram = Scruple × 12.95978

What Is a Scruple (Apothecary)?

A scruple is a traditional unit of mass used in the apothecaries' system, which was common in old pharmacy and medical prescriptions.

  • 1 Scruple = 20 grains
  • 1 Grain = 0.06479891 grams

Therefore:

1 Scruple = 20 × 0.06479891 grams

= 1.2959782 grams

What Is a Decigram?

A decigram (dg) is a metric unit of mass equal to one-tenth of a gram.

  • 1 Decigram = 0.1 gram
  • 10 Decigrams = 1 gram

Decigrams are part of the standard metric system used in laboratories, education, and scientific calculations.

Step-by-Step Conversion Logic

Step 1: Convert Scruple to Grams

1 Scruple = 1.2959782 grams

Step 2: Convert Grams to Decigrams

Since 1 gram = 10 decigrams:

1.2959782 × 10

Step 3: Calculate

= 12.959782 decigrams

Final Result:

1 Scruple (apothecary) = 12.95978 Decigrams

Conversion Formula

Decigram = Scruple × 12.95978

To convert back:

Scruple = Decigram ÷ 12.95978

Practical Examples

Example 1: Convert 1 Scruple

1 × 12.95978 = 12.95978 decigrams

Example 2: Convert 2 Scruples

2 × 12.95978 = 25.91956 decigrams

Example 3: Convert 0.5 Scruple

0.5 × 12.95978 = 6.47989 decigrams
