## Imperial to metric examples

### Mass

 Conversion factor Example Imperial tonsto metric tons x 1.016(approx) 1 imperial ton= 1 x 1.016= 1.016 metric ton Stones to kilograms(st to kg) x 6.350(approx) 1st = 1 x 6.350 = 6.350kg Pounds to kilograms(lb to kg) x 0.454(approx) 1lb = 1 x 0.454 = 0.454kg Ounces to grams(oz to g) x 28.350(approx) 1oz = 1 x 28.350 = 28.350g

(kilo denotes one thousand)

### Distance (length/height/width)

 Conversion factor Example Miles to kilometers(miles to km) x 1.609(approx) 1mile = 1 x 1.609 = 1.609km Yards to meters(yd to m) x 0.914(approx) 1yd = 1 x 0.914 = 0.914m Feet to meters(ft to m) x 0.305(approx) 1ft = 1 x 0.305 = 0.305m Inches to centimeters(in to cm) x 2.54 1in = 1 x 2.54 = 2.54cm

(centi denotes one hundredth)

### Area

 Conversionfactor Example Acres to hectares(ac to ha) x 0.405(approx) 1ac = 1 x 0.405 = 0.405ha Square yardsto square meters(yd² to m²) x 0.836(approx) 1yd² = 1 x 0.836 = 0.836m² Square feetto square meters(ft² to m²) x 0.093(approx) 1ft² = 1 x 0.093 = 0.093m² Square inchesto square centimeters(in² to cm²) x 6.452(approx) 1in² = 1 x 6.452 = 6.452cm²

### Volume / capacity

 Conversionfactor Example Cubic yardsto cubic meters(yd³ to m³) x 0.765(approx) 1yd³ = 1 x 0.765 = 0.765m³ Cubic feetto cubic meters(ft³ to m³) x 0.028(approx) 1ft³ = 1 x 0.028 = 0.028m³ Cubic inchesto cubic centimeters(in³ to cm³) x 16.387(approx) 1in³ = 1 x 16.387 = 16.387cm³ Imperial gallons to liters(imp gal to l) x 4.546(approx) 1 imp gal = 1 x 4.546 = 4.546l Imperial pints to liters(imp pt to l) x 0.568(approx) 1 imp pt = 1 x 0.568 = 0.568l

### Speed

 Conversionfactor Example Miles per hourto kilometers per hour(mph to km/hr) x 1.609(approx) 1mph = 1 x 1.609 = 1.609km/hr Yards per secondto meters per second(yd/s to m/s) x 0.914(approx) 1yd/s = 1 x 0.914 = 0.914m/s Feet per secondto meters per second(ft/s to m/s) x 0.305(approx) 1ft/s = 1 x 0.305 = 0.305m/s
