- Round the result
For simplicity, we round the result to two decimal places:
$$ 43.50 $$
70 km/h is approximately 43.50 mph
More Information
This conversion is commonly used in situations where speed limits or distances are given in different units, such as when traveling between countries with different measurement systems.
Tips
A common mistake is forgetting to use the correct conversion factor or mixing up the direction of conversion (e.g., converting from miles to kilometers instead of from kilometers to miles). Always double-check your conversion factors and units.
