Visual representation of 400 mph compared to other speeds:
Speed refers to how fast an object is moving. Two common units of speed measurement are:
- Miles per hour (mph): Primarily used in the United States and the United Kingdom.
- Kilometers per hour (kph): Used in most countries worldwide that follow the metric system.
The conversion between these units is based on the relationship between kilometers and miles:
1 mile = 1.60934 kilometers
Thus:
- To convert mph to kph: kph = mph × 1.6093
- To convert kph to mph: mph = kph × 0.6214
400 mph is exceptionally fast, typically achievable by:
- High-speed passenger trains
- Supersonic jets
- Formula 1 racing cars on certain circuits
Real-world speed contexts involving 400 mph:
