This converter allows you to convert long tons [tn.l.] to gigatons [Gt] or gigatons [Gt] to long tons [tn.l.]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 long ton [tn.l.] ≈ 1.016 * 10-9 gigatons [Gt]1 gigaton [Gt] ≈ 9.842 * 108 long tons [tn.l.]

Convert long tons to gigatons

There are two simple ways to convert long tons [tn.l.] to gigatons [Gt]. In the first calculation method, the value in long tons [tn.l.] is divided by the rounded conversion factor of 9.842 * 108. The second method multiplies the value in long tons [tn.l.] by the rounded conversion factor of 1.016 * 10-9.

  • Gigatons [Gt] ≈ long tons [tn.l.] ÷ (9.842 * 108)
  • Gigatons [Gt] ≈ long tons [tn.l.] * 1.016 * 10-9

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of long tons [tn.l.] to gigatons [Gt] can be achieved using the following calculation method.

  • Gigatons [Gt] = long tons [tn.l.] * 971.68 * 1,045.66 ÷ 1015

Convert gigatons to long tons

Converting gigatons [Gt] to long tons [tn.l.] is easy and can be done in two ways. The first method involves multiplication, in which the value in gigatons [Gt] is multiplied by the rounded conversion factor of 9.842 * 108. The second variant is a division. Here, the value in gigatons [Gt] is divided by the rounded conversion factor of 1.016 * 10-9.

  • Long tons [tn.l.] ≈ gigatons [Gt] * 9.842 * 108
  • Long tons [tn.l.] ≈ gigatons [Gt] ÷ (1.016 * 10-9)

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of gigatons [Gt] to long tons [tn.l.] can be achieved using the following calculation method.

  • Long tons [tn.l.] = gigatons [Gt] ÷ 971.68 ÷ 1,045.66 * 1015
