Question

How do you convert 6.1 lbs to kg?

Answer 1

`6.1 "lb" = 2.766913457"kg" ~~ 2.77"kg"`

Explanation:

There are `1000` grams in a kilogram.

`1 "lb"` is defined as exactly `453.59237"g"`

So:

`6.1 "lb" = 6.1 xx 453.59237"g" = 2766.913457"g" = 2.766913457"kg"`

If you are calculating by hand and only need an approximation, then you might use `1"lb" ~~ 0.454"kg"` to find:

`6.1 "lb" ~~ 6.1 xx 0.454"kg" ~~ 2.77"kg"`
