Formula
US Short Tons = Pounds ÷ 2,000
UK Long Tons = Pounds ÷ 2,240
Metric Tons = Kilograms ÷ 1,000
Pounds = Kilograms × 2.20462
Metric Tons = Pounds ÷ 2,204.62
Example 1: Convert 2,000 pounds to tons
Step 1: US short tons: 2,000 ÷ 2,000 = 1 ton
Step 2: UK long tons: 2,000 ÷ 2,240 = 0.893 tons
Step 3: Kilograms: 2,000 × 0.453592 = 907.18 kg
Step 4: Metric tons: 907.18 ÷ 1,000 = 0.907 metric tons
Example 2: Convert 5 metric tons to other units
Step 1: Kilograms: 5 × 1,000 = 5,000 kg
Step 2: Pounds: 5,000 × 2.20462 = 11,023.1 lbs
Step 3: US short tons: 11,023.1 ÷ 2,000 = 5.51 tons
Step 4: UK long tons: 11,023.1 ÷ 2,240 = 4.92 tons
