Convert stones to tons (metric and imperial) for accurate weight calculations in shipping, construction, and trade. Understand the differences between metric tons, short tons, and long tons.
1 stone equals 0.006350294971201412 ton
Formula: ton = st × 0.00700000
Understanding stone to ton conversion is essential for professionals working with weight measurements across different systems. One stone equals 0.00635029 metric tons (6.35029 kilograms), while the relationship to short tons (US) and long tons (UK) differs significantly. This conversion matters greatly in international shipping, construction materials, and trade where weight specifications directly impact costs and compliance.
Weight measurement accuracy directly affects shipping costs, construction budgets, and legal compliance. Miscalculating stone to ton conversions can result in overcharging or undercharging by thousands of dollars on large shipments. In the UK construction industry, material specifications often use stones while international contracts require metric tons or short tons, making precise conversion critical for project success and regulatory adherence.
Shipping companies and logistics professionals must convert weight measurements to calculate freight costs, vessel capacity, and regulatory compliance. Stone measurements common in UK documentation must be converted to metric tons for EU shipments or short tons for US destinations. Accurate conversion prevents overweight penalties, ensures proper load distribution, and maintains insurance compliance across international borders.
Construction suppliers and project managers specify material quantities in stones (particularly in UK) but must convert to metric tons for international projects and EU compliance documentation. Concrete, gravel, sand, and steel reinforcement are often quoted in stones locally but invoiced in metric tons for large-scale projects. Accurate conversion ensures material budgets align with project specifications and prevents costly over-orders or shortages.

This stone to ton converter uses high-precision conversion factors to ensure accurate results for professional and academic use.
Our calculator provides results with up to 10 decimal places for maximum accuracy.
One metric ton equals 157.47 stones (exactly 1,000 kg ÷ 6.35029 kg per stone). One short ton (US) equals 142.86 stones (2,000 lbs ÷ 14 lbs per stone). One long ton (UK) equals 160 stones (2,240 lbs ÷ 14 lbs per stone). The answer depends entirely on which 'ton' your contract specifies. For international trade, always assume metric ton unless otherwise stated.
The short ton (2,000 lbs) became standard in the United States because it's exactly 1,000 short hundredweights (100 lbs each). The long ton (2,240 lbs) remained in the UK because it equals exactly 20 long hundredweights (112 lbs each). These systems developed independently before metrication. Today, the metric ton is the international standard for most commerce, but US short tons persist in American domestic trade, creating complexity in transatlantic shipping where conversions are essential.
