FAQ

Why is 0.4 equal to 0.40 and 0.400?
Because 4 tenths (4/10) is equivalent to 40 hundredths (40/100) and 400 thousandths (400/1000); adding zeros to the extreme right of the decimal part adds 0 hundredths and 0 thousandths, leaving the value unchanged.

How do you convert millimetres to centimetres and grams to kilograms using decimals?
Since 1 cm = 10 mm, 1 mm = 1/10 cm = 0.1 cm. Since 1 kg = 1000 g, 1 g = 1/1000 kg = 0.001 kg.
