How it is calculated
The kilogram is the SI base unit of mass; the pound is defined from it. That makes the conversion one multiplication, with an exact factor rather than a rule of thumb.
pounds = kilograms × 2.2046226218 · ounces = (pounds − whole pounds) × 16
Start from the definition
The international avoirdupois pound is defined as exactly 0.45359237 kg. One kilogram is therefore 1 ÷ 0.45359237 = 2.2046226218 lb — the factor the calculator uses.
Multiply, do not guess
70 kg × 2.2046226218 = 154.3236 lb. The 2.2 figure people use in conversation is rounded, and on 70 kg it is already about 0.3 lb short.
Split the fraction into ounces
Take the whole pounds and multiply the decimal remainder by 16, because a pound has 16 ounces. 0.3236 lb × 16 = 5.2 oz, so 70 kg is 154 lb 5.2 oz.

What most pages get wrong
The pound is defined from the kilogram
One pound is exactly 0.45359237 kg by international agreement. The 2.2046 figure is simply 1 divided by that number, which is why it has so many decimal places.
A pound has 16 ounces, and an ounce is 28.35 g
Ounces are useful for small weights: 0.5 kg is 1 lb 1.6 oz, and one ounce is 28.3495 g. The calculator shows both the decimal pound figure and the pounds + ounces reading.
23 kg is 50.7 lb
Indian tickets usually state baggage allowances in kg, while some international tickets and shipping labels use lb. A 50 lb limit is 22.68 kg, so 23 kg is slightly over it.
Gym scales and imported devices may show pounds
An Indian bathroom scale shows kg; some gym machines and foreign fitness apps default to lb. 70 kg reads as 154.3 lb, not 154 lb exactly.
