Like metric system units, imperial units are used to measure quantities such as mass, distance, area, volume/capacity and speed.
They include pounds, yards, square and cubic yards, imperial gallons and miles per hour.

Example | ||
Imperial tons to stones (imperial tons to st) |
x 160 |
1 imperial ton = 1 x 160 = 160 stones | |
Stones to imperial tons (st to imperial tons) |
÷ 160 |
160 stones = 160 ÷ 160 = 1 imperial ton | |
Stones to pounds (st to lb) |
x 14 |
1st = 1 x 14 = 14lb | |
Pounds to stones (lb to st) |
÷ 14 |
14lb = 14 ÷ 14 = 1st | |
Pounds to ounces (lb to oz) |
x 16 |
1lb = 1 x 16 = 16oz | |
Ounces to pounds (oz to lb) |
÷ 16 |
16oz = 16 ÷ 16 = 1lb |
Conversion factor |
Example | ||
Miles to yards (miles to yd) |
x 1760 |
1 mile = 1 x 1760 = 1760yd | |
Yards to miles (yd to miles) |
÷ 1760 |
1760yd = 1760 ÷ 1760 = 1 mile | |
Yards to feet (yd to ft) |
x 3 |
1yd = 1 x 3 = 3ft | |
Feet to yards (ft to yd) |
÷ 3 |
3ft = 3 ÷ 3 = 1yd | |
Feet to inches (ft to in) |
x 12 |
1ft = 1 x 12 = 12in | |
Inches to feet (in to ft) |
÷ 12 |
12in = 12 ÷ 12 = 1ft |
Conversion factor |
Example | ||
Acres to square yards (ac to yd²) |
x 4840 |
1ac = 1 x 4840 = 4840yd² | |
Square yards to acres (yd² to ac) |
÷ 4840 |
4840yd² = 4840 ÷ 4840 = 1ac | |
Square yards to square feet (yd² to ft²) |
x 9 |
1yd² = 1 x 9 = 9ft² | |
Square feet to square yards (ft² to yd²) |
÷ 9 |
9ft² = 9 ÷ 9 = 1yd² | |
Square feet to square inches (ft² to in²) |
x 144 |
1ft² = 1 x 144 = 144in² | |
Square inches to square feet (in² to ft²) |
÷ 144 |
144in² = 144 ÷ 144 = 1ft² |
Note
Conversion factor |
Example | ||
Cubic yards to cubic feet (yd³ to ft³) |
x 27 |
1yd³ = 1 x 27 = 27ft³ | |
Cubic feet to cubic yards (ft³ to yd³) |
÷ 27 |
27ft³ = 27 ÷ 27= 1yd³ | |
Cubic feet to cubic inches (ft³ to in³) |
x 1728 |
1ft³ = 1 x 1728 = 1728in³ | |
Cubic inches to cubic feet (in³ to ft³) |
÷ 1728 |
1728in³ = 1728 ÷ 1728 = 1ft³ | |
Imperial gallons to imperial pints (imp gal to imp pt) |
x 8 |
1 imp gal = 1 x 8 = 8 imp pt | |
Imperial pints to imperial gallons (imp pt to imp gal) |
÷ 8 |
8 imp pt = 8 ÷ 8 = 1 imp gal |
Note

Conversion factor |
Example | ||
Miles per hour to yards per second (yd/s to mph) |
÷ 2.045 (approx) |
2.045mph = 2.045 ÷ 2.045 = 1yd/s | |
Yards per second to miles per hour (yd/s to mph) |
x 2.045 (approx) |
1yd/s = 1 x 2.045 = 2.045mph | |
Miles per hour to feet per second (mph to ft/s) |
÷ 0.682 (approx) |
0.682mph = 0.682 ÷ 0.682 = 1ft/s | |
Feet per second to miles per hour (ft/s to mph) |
x 0.682 (approx) |
1ft/s = 1 x 0.682 = 0.682mph |
