Convert stones to long tons for accurate weight calculations in shipping, agriculture, and British industry. Precise conversion factor: 1 stone = 0.00625 long tons. Essential for international trade.
1 stone equals 0.006250004762721228 long ton
Formula: long tn = st × 0.00625000
The stone and long ton represent two distinct weight measurements primarily used in the United Kingdom and Commonwealth nations. With 1 stone equaling exactly 0.00625 long tons (or 1 long ton equaling 160 stones), understanding this conversion is essential for professionals in agriculture, shipping, and trade. These imperial measurements remain deeply embedded in British industry despite global metric adoption.
Weight measurement accuracy directly impacts shipping costs, agricultural commodity pricing, and regulatory compliance in Commonwealth nations. A 1% conversion error on a 500-stone shipment would result in an 5-stone (31.75 kg) discrepancy, potentially costing hundreds of pounds in miscalculated freight fees or commodity transactions. Legal contracts for goods sold by weight require precise conversions to prevent disputes.
British farmers and grain merchants routinely trade agricultural products using stones and long tons. Export markets require accurate conversion between imperial measurements and metric systems. Livestock weights, grain yields, and fertilizer quantities are calculated using these conversions for both domestic sales and international export documentation.
UK ports and shipping companies use long tons as the standard measurement for cargo weight, while many goods arrive documented in stones. Port operators, customs officials, and logistics coordinators must accurately convert between these measurements for manifest documentation, cargo fees, and regulatory compliance. Shipping containers and cargo holds are typically rated in long tons.

Exactly 160 stones equal 1 long ton. This relationship is precise and defined by law: 1 long ton = 2,240 pounds, and 1 stone = 14 pounds. Therefore, 2,240 ÷ 14 = 160 stones per long ton. To convert stones to long tons, divide the number of stones by 160 or multiply by 0.00625. For example, 480 stones = 3 long tons exactly.
The stone persists in British culture due to historical tradition and institutional inertia. Personal body weight measurement in stones remains deeply embedded in healthcare, fitness, and casual conversation despite official metric adoption in 1965. UK law permits both imperial and metric measurements in commerce, and the older generation continues using stones naturally. The measurement is so culturally significant that British bathroom scales are often dual-marked with both stones and kilograms.
