ギガメートル
1. GigametreA gigametre is a unit of length in the metric system, equal to one billion metres, the SI base unit of length, hence to 1,000,000 km or approximately 621,370 miles. Gigametres (from the Greek words gigas = giant and metro = count/measure) are rarely seen in practical use, because they are too big for any terrestrial tasks. However, gigametres are sometimes used in astronomy to measure the distance of companion objects such as planets from their stars including our Sun.
