Do you need to convert grams (g) to pounds (lbs), or pounds to grams? It's easy to do. All you need to know is that 1 g = 0.0022 lbs, and thus 1 lb = 453.6 g.^{[1]

Converting Grams to Pounds

1
Convert 1 gram to .0022lbs. Every single gram is only about .2% of a pound, or .0022lbs. So, $1g=.0022lbs$ $1g=.0022lbs$ , and every additional gram adds another .0022 pounds. Thus, $2g=.0044lbs$ $2g=.0044lbs$ , $3=.0066lbs$ $3=.0066lbs$ , and so on. Thought of another way, this means there are .0022 pounds per gram.^{[2]

- If you remember that a kilogram weighs 2.2 pounds, this conversion is much easier. After all, 1 kilogram = 1000 grams. So, 1 gram must be one one-thousandth the weight of a kilogram, or .0022lbs.^{[3]

Multiply your number of grams to by .0022 to convert to pounds. This is all it takes. Simply multiply the grams by the pounds per gram, .0022, to convert everything simply into pounds.^{[4]

- $20g=lbs$ $20g=lbs$
  - $20g*.0022{\frac {lbs}{g}}$
  - 20g = .044 lbs
- $12492g=lbs$ $12492g=lbs$
  - $12492g*.0022{\frac {lbs}{g}}$
  - 12492g = 27.48 lbs

Converting Without a Calculator

1
Estimate the conversion by multiplying the grams by two, then moving the decimal three places to the left. Left without a calculator? You can still get a rough approximation of the conversion using basic math in place of long decimal division. This trick simply re-writes .0022 so that $.0022={\frac {2.2}{1000}}$ $.0022={\frac {2.2}{1000}}$ Furthermore, you can simplify your estimation by simply using "2" instead of 2.2. You must remember, however, that this estimation will always underestimate the actual answer, an issue that gets bigger the bigger the number converted:
- $20g=lbs$
- $20g*2=40$
- ${\frac {40}{1000}}=.0004$
- Estimated Answer: .0004
- $12492g=lbs$
- $12492g*2=24984$
- ${\frac {24984}{1000}}=24.98$
- Estimated Answer: 24.98
2
Get the perfect answer without a calculator by adding back 10% of your estimation. When simplifying the problem in the last step, you used .002 instead of .0022 to get an estimation. But .0022 is really just .002 + .0002 = .0022. You just figured out how to get .002 grams in your last step -- you simply multiply by 2, then divide by 1000. For the second half, you just multiply by 2 and divide by 10,000, giving you .0002. But you already did most of the work! Just divide your estimation by ten and then add this answer back to the estimation. Seen in full:
- Convert 12492 grams to pounds:
  - $1g=.0022lbs$
  - $.0022lbs=.002lbs+.0002lbs$
- Step 1-- Find .002 lbs estimation
  - $12492g*2=24984$
  - ${\frac {24984}{1000}}=24.98$
- Step 2-- Find .0002 lbs estimation
  - ${\frac {24.98}{10}}=2.498$
- Step 3 -- Add the two estimations together
  - $24.98+2.498=27.48lbs$
- 12492g = 27.48 lbs This is the same answer as the calculator conversion used above!
