When you say 'kilo', I'm assuming you mean 'kilogram' since you're discussing force.
On Earth, 1 kilogram of mass weighs 2.205 pounds. (rounded) 7 kilograms of mass
weigh 15.43 pounds. (rounded)
In other places, the same 7 kilograms of mass has a different weight.
The same way you round to the nearest anything. You eliminate the numbers after the decimal point; if the first decimal digit decimal digit is 5 or more, you add one to the whole part.
For three significant digits, this number has to be rounded at the ones place. So if you look at the number after the ones place (8), you see that you need to round up. The final answer is 45.0 - the zero after the decimal is significant.
Because conversion in the decimal system is based on multiplication (or division) by powers of ten. Each multiplication by ten is equivalent to moving the decimal point one place to the right.
There are 1447.8 millimetres to 57 inches to 1 decimal place.
15mm - you just times it by 10!! (move the decimal place 1 place to the right)!
