# How accurate is the tola measurement compared to grams?

The tola is a highly reliable unit of measurement—especially in the context of gold trading—but it is not as precise or universally standardised as the **gram**, which is part of the I**nternational System of Units (SI)**.

Here’s a refined comparison:

### Accuracy of Tola vs Grams

**1 tola = 11.6638038 grams** (precisely defined under British India in 1833)

In **modern practice**, the tola is typically **rounded to 11.66 grams** for convenience.

In the **jewellery industry**, especially in South Asia, tola is often used informally to mean 10 grams when referring to gold ornaments, not coins or bullion.

### Compared to Grams:

The **gram** is a globally accepted metric unit, traceable to the International Bureau of Weights and Measures (BIPM).

The **tola**, while historically standardised, can **vary slightly by region** or context, especially in informal settings.

### Summary:

| Unit | Official Value | Used For | Precision |
| --- | --- | --- | --- |
| Tola | 11.6638 g (standard) | Coins, bullion, and traditional gold | High (formal), Medium (informal) |
| Gram | 1 g (exact, SI unit) | All scientific and commercial uses | Very High |

### Tola

 **Official Value:** 11.6638 g (standard) **Used For:** Coins, bullion, and traditional gold **Precision:** High (formal), Medium (informal)

### Gram

 **Official Value:** 1 g (exact, SI unit) **Used For:** All scientific and commercial uses **Precision:** Very High

**At PureJewels**, we distinguish this clearly:

- **Coins and bullion:** 1 tola = **11.66g**
- **Jewellery :** 1 tola =**10g**

This ensures both cultural continuity and modern precision, so you can shop or invest with confidence.
