# Distance calculator

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 = `299 792 458 m/s`
• Speed = `3 * 108 m/s (scientific)`
• Speed = `299.79 * 106 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 = `1 079 252 848 800 m/hr`
• Speed = `983 571 056 ft/sec`
• ### Time

• Time = `31 556 736 secs` = `1.0 yrs`
• = `31.56 * 106 sec(s)`
• = `525.95 * 103 min(s)`
• = `8.77 * 103 hr(s)`
• = `365.24 day(s)`
• = `52.18 wk(s)`
• = `1 year(s)`
• ### Speed x Time = Distance

• Distance = `9 460 471 451 897 088 meter`
• = `63.24 * 103 astronomical unit`
• = `9.46 petametre`
• = `999.97 * 10-3 lightyear`
• = `306.59 * 10-3 parsec`
