How do I calculate this example: 10 lb?

4.5359237 kg. This is a calculated example under the model stated above; it is not a measured component specification.

Which units does Mass Converter: kg, Grams, Pounds, Ounces and Tons use?

mg, g, kg, t, lb, oz, US ton, UK ton. Convert prefixes before substituting values; keep the input and output units attached to every number.

Can I convert kg directly to N?

Multiply mass by gravitational acceleration: W = mg. At standard gravity, 1 kg has weight 9.80665 N; this is not a mass-unit conversion.

Are oz and troy oz the same?

No. This tool uses the avoirdupois ounce, 28.349523125 g. A troy ounce is 31.1034768 g and is not the oz option here.
