What is the issue?The world measures are far from standard and we run multiple measures of temperature, distance, space etc depending upon which activity undertaken or nation we happen to be in.
Why address this?To make sense of the data we need to use conversion tables
How to address this?Here is a list of useful conversion tables that may turn out convenient.
To convert degrees Celsius into degrees Fahrenheit….Multiply by 1.8 and add 32
To convert degrees Fahrenheit to degrees Celsius….Subtract 32 and divide by 1.8
To convert Pounds (Ib) to Kilogrammes (kg) ....multiply by 0.4536
To convert Kilogrammes to Pounds .....multiply by 2.205
Water 1 litre weighs 1.00 kg/2.2 lb.
1 gallon weighs 4.53 kg/10 lb.
To convert Gallons to Litres ....multiply by 4.546
To convert Litres to Gallons ....multiply by 0.22
To convert Petrol to Weight ....1 litre weighs 0.73 kg/1.61 lb. 1 gallon weighs 3.36 kg/7.4 lb.
To convert Diesel to Weight .....1 litre weighs 0.84 kg/1.85 Ib.1 gallon weighs 3.86 kg/8.5 lb.
1 Imperial Gallon = 4.546 litres = 1.2 US Gallons
1 litre = 0.22 Imperial gallons = 0.264 US Gallons
1 US Gallon = 3.8 litres = 0.83 Imperial Gallons
Space and distance
To convert cubic feet to cubic metres .....multiply by 0.028
To convert 1 cu ft to fluid capacity .....it holds 6114 gallons of water weighing 62.31b
To convert square metres to square feet .....multiply by 10.764
To convert square feet to square metres .....multiply by 0.093
To convert square centimetres to square feet .....multiply by 0.001076
To convert square inches to square centimetres .....multiply by 6.451
1 knot = 1.1508 mph = 1.853 kmph
To convert Kilometres per hour to Miles per hour .....multiply by 0.6214
To convert Miles per hour to Kilometres per hour ....multiply by 1.609
To convert Kilometres per hour to Knots per hour ....multiply by 0.5396
To convert Knots per hour to Kilometres per hour ....multiply by 1.853
Amps equals watts divided by volts.
To convert Inches to Centimetres (cm) ....multiply by 2.54
To convert Centimetres to Inches .....multiply by 0.393
1 foot = 30.48 centimetres (cm)
1 yard = 0.9144 metre (m)
1 mile = 1.6093 kilometres (km)
1 millimetre = 0.03937 inch
1 centimetre = 0.0328 foot (ft)
1 metre = 1.094 yards (yd)
1 kilometre = 0.62137 mile
1 nautical mile = 1852 m
1 International mile = 1609.344 m
Quick and dirty conversions
Metres into yards add one-tenth
Yards into metres deduct one-tenth
Kilometres into miles multiply by 5 and divide by 8
Miles into kilometres multiply by 8 and divide by 5
Litres into pints multiply by 7 and divide by 4
Pints into litres multiply by 4 and divide by 7
Litres into gallons multiply by 2 and divide by 9
Gallons into litres multiply by 9 and divide by 2
Kilogrammes into pounds divide by 9 and multiply bv 20
