### Calculation process of conversion value

• 1 atomic mass unit, unified = (1.66053904*10^-27) / (1000) = 1.66053904 × 10-30 tonne
• 1 tonne = (1000) / (1.66053904*10^-27) = 6.0221408585492 × 10+29 atomic mass unit, unified
• ? atomic mass unit, unified × (1.66053904*10^-27  ("kg"/"atomic mass unit, unified")) / (1000  ("kg"/"tonne")) = ? tonne

### High precision conversion

If conversion between atomic mass unit, unified to kilogram and kilogram to tonne is exactly definied, high precision conversion from atomic mass unit, unified to tonne is enabled.

Since definition contain rounded number(s) too, there is no sense for high precision calculation, but if you want, you can enable it. Keep in mind, that converted number will be inaccurate due this rounding error!
