SUMMARY

The conversion from milligrams (mg) to kilograms (kg) is achieved by multiplying the value in mg by 10^-6. For example, to convert 1250 mg to kg, the calculation is 1250 mg × 10^-6 kg/mg, resulting in 0.00125 kg. A method to aid understanding of unit conversions is the "multiplying by 1" technique, which maintains the value while changing the units. While tools like Wolfram Alpha can perform these conversions, they may not provide clarity on the underlying process.

PREREQUISITES
  • Understanding of metric prefixes, specifically milli- and kilo-
  • Basic knowledge of unit conversion principles
  • Familiarity with dimensional analysis
  • Ability to perform multiplication with scientific notation
NEXT STEPS

Hi

I want help to convert mg to kg

ex: 1250mg --- > kg

Are we multiply 1250mg X 10^-3

or multiply 1250mg X 10^-6


I want your help >>

One way that I've found helps students that are new to unit conversions understand is called "multiplying by 1" In any expression, I can multiply by 1 as many times as I want without changing the answer. To see how this works, let's take you question, as follows:
1250 mg = 1250 mg \frac{1 g}{1000 mg} \frac{1kg}{1000g} = \frac{1250 kg}{10^6} = 1250 \times 10^{-6} kg

Does this help? The problem with Wolfram Alpha is that, while it works, you don't usually know what it is doing.
