# Velocity calculator: `Bugatti Veyron top speed: 435 km/hr`

This calculator helps you estimate the distance travelled after a certain time of constant speed. It also converts to alternative speed units: mile/hr, km/h, m/s, mach, ...

### Speed

##### METRIC (DECIMAL)

Most countries use the Metric System, which uses the measuring units such as meters and grams and adds prefixes like kilo, milli and centi to count orders of magnitude.

• Speed = `1 128 m/s`
• Speed = `1.13 * 103 m/s (scientific)`
• Speed = `1.13 * 103 m/s (engineering)`
• ##### IMPERIAL

In the USA and UK, the older Imperial system is used, where things are measured in feet, inches and pounds.

• Speed = `4 060 001 m/hr`
• Speed = `3 700 ft/sec`
• ### Time

• Time = `604 800 secs` = `1.0 wks`
• = `604.8 * 103 sec(s)`
• = `10.08 * 103 min(s)`
• = `168 hr(s)`
• = `7 day(s)`
• = `1 wk(s)`
• ### Speed x Time = Distance

• Distance = `682 080 135 meter`
• = `682.08 * 103 km`
• = `423.83 * 103 mile`
• = `368.29 * 103 nautical mile`
