OPINION

PER CURIAM:

Leroy Davis and Jermel Alston appeal their 235-month sentences
imposed after their guilty pleas to conspiracy to distribute and possess
with intent to distribute cocaine powder and crack cocaine. They chal-
lenge the district court's determination that the amount of crack
cocaine attributable to each of them was 1200 grams. Alston has
moved to file a supplemental pro se brief challenging the voluntari-
ness of his plea and the determination of the quantity of crack cocaine
attributable to him. We grant the motion to file the supplemental brief
and affirm.

Alston pled guilty to the charge in the indictment, which included
both powder and crack cocaine. His plea was without the benefit of
a plea agreement limiting his participation. Alston now asserts that he
thought he was pleading guilty to a powder cocaine conspiracy only.
Because Alston's plea constitutes an admission of the material ele-
ments of the crime charged, see McCarthy v. United States, 394 U.S.
459, 466 (1969), he cannot now invalidate his plea by stating that he
intended to plead guilty to participation in a drug conspiracy whose
primary substance was powder cocaine. The type and quantity of
drugs was left open by the plea, and the government had the burden
of proving these by a preponderance of the evidence. See United
States v. Gilliam, 987 F.2d 1009, 1013 (4th Cir. 1993).

The calculation of the quantity of drugs attributable to a defendant
is a factual determination, which should be upheld unless clearly erro-

                    2
neous. See United States v. Goff, 907 F.2d 1441, 1444 (4th Cir. 1990).
The court may estimate, if necessary, the amount of drugs which are
part of the defendant's relevant conduct, taking into consideration
similar known transactions. United States Sentencing Commission,
Guidelines Manual, § 2D1.1, comment. (n.12) (Nov. 1995); United
States v. Johnson, 943 F.2d 383, 387-88 (4th Cir. 1991). The sentenc-
ing court may consider hearsay testimony to establish drug quantities.
See United States v. Bowman, 926 F.2d 380, 381 (4th Cir. 1991).

Special Agent Chris C. Jackson of the Drug Enforcement Adminis-
tration ("DEA") testified at the sentencing hearing that Tammy
Wortham was approached by Alston about becoming a drug courier
between Henderson, North Carolina and New York City. Alston then
introduced Wortham to Davis.

On behalf of both Alston and Davis, Wortham made ten to twelve
trips to New York and brought back cocaine. She initially transported
grapefruit-sized packages, which Agent Jackson stated weighed
approximately eight or nine ounces each. The package size increased
until Wortham was arrested with 345 grams of cocaine powder.
Wortham stated that she had transported one other package that was
the same size as the one she had when arrested and several that were
a bit smaller, which Agent Jackson estimated at 300 grams each.
Wortham was paid after each trip with one-fourth to one-third of an
ounce of crack cocaine.

The total amount of cocaine Wortham transported from New York
to Henderson was estimated at 3095 grams. Special Agent Jackson
also testified that although Wortham was arrested while transporting
powder cocaine, she was always paid in crack cocaine. Three other
women who made trips for Defendants were also paid with crack.
Additionally, Jackson testified that Wortham told him about a trip she
made with the Defendants to shop for a cooker--a device used to con-
vert cocaine powder to crack. Also, five drug dealers who had deal-
ings with Alston and Davis told Agent Jackson that they had always
obtained crack, not powder, from Defendants.

Jackson testified that, according to the DEA lab, when a kilogram
of powder cocaine is cooked, it results in 800 grams of crack cocaine.
Cf. United States v. Hyppolite, 65 F.3d 1151, 1158 (4th Cir. 1995)

                    3
(citing United States v. Ricco, 52 F.3d 58, 63 n.5 (4th Cir.), cert.
denied, ___ U. S. ___, 64 U.S.L.W. 3247 (U.S. Oct. 2, 1995) (No. 95-
5502)), cert. denied, ___ U.S. #6D6D 6D#, 64 U.S.L.W. 708 (U.S. Apr. 22,
1996) (No. 95-8395). The sentencing court conservatively estimated
that less than half of the 3095 grams of powder was converted to
crack cocaine, yielding 1200 grams of crack.

Based on the evidence that Defendants' dealings were in crack
cocaine and the absence of evidence of any distribution of cocaine
powder, this finding as to the quantity of crack cocaine attributable
to the Defendants is supported by the preponderance of the evidence,
see Gilliam, 987 F.2d at 1013, and is not clearly erroneous. See Goff,
907 F.2d at 1444.

Therefore, we affirm Alston's conviction and affirm the Defen-
dants' sentences. We dispense with oral argument because the facts
and legal contentions are adequately presented in the materials before
the court and argument would not aid the decisional process.
