§03Practical Example

Step-by-step walkthrough

Scenario

Convert 5 kilocalories to ergs.

  1. 01Look up the SI factors: 1 kilocalorie = 4184 base units, 1 erg = 1e-7 base units.
  2. 02Divide to get the conversion ratio: 4184 / 1e-7 = 4.18400e+10.
  3. 03Multiply by the quantity: 5 × 4.18400e+10 = 2.09200e+11.
  4. 04So 5 kilocalories = 2.09200e+11 ergs.
