Units explained
Gram
The gram (g) equals one-thousandth of a kilogram.
From Late Latin 'gramma', a small weight or scruple.
The everyday metric unit for food, medicine, and small objects.
Defined in 1795 as the mass of one cubic centimeter of water at melting point.
Metric Ton
The metric ton (t) equals exactly 1,000 kilograms; it is also called the tonne.
From 'tun', a large medieval cask; 'metric' distinguishes it from imperial tons.
The global standard for trade, freight, and heavy industry.
Recognized internationally with the spread of the metric system in the late 19th century.
Gram to Metric Ton conversion formula
The relationship between grams and metric tons:
To convert grams to metric tons, multiply the value in grams by 1e-6. To reverse, multiply metric tons by 1000000.

Step-by-step: convert grams to metric tons
- Write down the value in grams (g).
- Multiply that value by the factor 1e-6.
- The product is the equivalent value in metric tons (t).
- To reverse, multiply the metric ton value by 1000000.
Worked examples
Example 1 — Convert 1 g to t:
1 × 1e-6 = 1e-6 t
Example 2 — Convert 100 g to t:
100 × 1e-6 = 1e-4 t
Real-world example — Architectural to geographic scale
A 100,000-gram measurement equals one metric ton. The five-order-of-magnitude scale change comes up in mapping work where architectural site plans must be related to road-network maps.
100000 g × 1e-6 = 0.1 t
Real-world example — Small to geographic-scale
100,000 grams equals one metric ton — a useful conversion when small-scale survey diagrams must be related to road-network distances on a different map.
100000 g × 1e-6 = 0.1 t
